BlueMagic32 | Blackmagic Bluetooth Arduino Library

PostFri Nov 29, 2019 3:50 am

Since I’ve learned about the Bluetooth functionality of the Blackmagic Cameras earlier this year, I’ve sought to bring functional and interesting hardware/software implementations to these great cameras.

To help aid in the pursuit, I’ve been developing an easy-to-use Arduino library, to enable anyone to build their own Bluetooth controllers. From experienced programmers to newcomers, should be very flexible to use.

The library is still in development and will soon be available and I highly encourage people to extend/improve this library as they see fit when it becomes available. ( likely could use some under the hood improvements as It’s my first time developing C++ Library )

Here’s an early look at a really simple piece of demo code that can create a remote trigger with live timecode ( using a $15 development device ) and an example of an integration with a Samsung Gear VR Remote to control the camera. ( really cool possibilities with this as it has lots of buttons, a touchpad, gyroscope/accelerometer and is widely available and cost effective.)

Still working on adding an example or two, would love to hear what kind of examples you’d like to see included with the library and I’ll see If I can make those happen.

Hi Csaba,

great job indeed!
I am wondering why everyone is adding additional hardware to their circuits (e.g. M5StickC, WifiKit 32 or anything based on the ESP32 chip) to control the BMPCC.
Samsung VR remote or Tilta Nucleous Nano in another case.

I managed (with a ton of help!) to successfully add a cheap potentiometer to the board to control the aperture via Bluetooth.
Unfortunately I was still to busy to write better code to "debounce" the reading of the potentiometer.
I will be a long cold winter...
(The original controlling code was not written by myself! I am not sure if the kind developer is part of this community.)

I am really looking forward to see your library!
It would bet great to change the aperture via a rotary encoder instead of a potentiometer.
This might be more reliable.

I have just received my M5StickC today...

Thank you,
Chris

Hello Csaba!

I'm really excited about this! I tried to do a simple ble controller for pocket 4k a year ago but got stuck in the bonding problems with nFR52 Arduino board.
So I'd love to see examples for bonding and sending simple commands for REC/STOP and manual focus. That would be great!
If you need a beta tester, I'm happy to help :)
Thanks for the awesome work in advance!

Pleased to announce to release of the BlueMagic32 Library! BlueMagic32 is an Arduino Library for controlling Blackmagic Cameras over Bluetooth Low Energy using an ESP32 device.

Link to library: https://github.com/schoolpost/BlueMagic32

Create your own Bluetooth control hardware that can control parameters such as:
-Recording
-Focus
-Frame Rate
-ISO
-Shutter
-Whitebalance/Tint

Use the provided examples and create a basic remote trigger in under 10 minutes! Watch the video guide and see for yourself.



As with any version 1.0; bugs and other quirks to be expected also some features are not yet fully implemented so be patient as they will be added soon. Please track bugs/problems with the github issues tool.

Can’t wait to see what everyone makes! ;)

Hi all,

just a quick hit, which would have saved me two hours...

If you follow all the instructions on OSX Catalina you will probably run into this error while uploading a Sketch to the M5StickC board.

A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header

I found the solution with a lot of searching the web (on a different computer, so I can not post the link).

The solution was fairly simple:
Just connect the port "G0" with ground "GND" using e.g. a paper clip.


BTW: Has anyone enhanced the capabilities of the sample code to controlling the aperture using rotary encoder?
This will be my next step.

Hi,

it seem that you are trying to flash the wrong board.
My Arduino IDE says "Board: M5Stick-C".

Try to follow the instructions step by step:
https://github.com/schoolpost/BlueMagic32

On OSX 10.14 it worked instantly (while the M5StickC was running).
For OSX 10.15 feel free to try my advice above.

I used this sketch:
https://github.com/schoolpost/BlueMagic ... a_Settings

Good luck - or send me a message.

Hi Max,

yes, I build a prototype remote aperture controller for a BMPCC 6K.

Meanwhile I am working on a Multicam Remote Aperture Controller using BLE, Wifi and LoRa to control cameras of multiple manufacturers like Blackmagic, Sony, Panasonic and ZCam.

Hi Chris,

of course, connection will be the only thing which I'm interested in.

First/initial Setup:

Visiual Studio Code with PlatformIO
ESP32 Dev Module
Example sketch from BlueMagic32 library
No errors

First episode:
Uploading sketch-->serial monitor is asking for pin-->camera is showing pin-->entering in serial monitor-->ESP does not connecting an repead the pairing process several times (~5)-->ESP stops asking for pin code and camera do not has no bluetooth connection at all. There were a short message on camera screen (bluetooth connection error).

Second episode:
trying same with new uploaded sketch ( platformIO and Arduino IDE )-->esp does not start to connect to camera ( no pin an camera shown/serial monitor is not asking for input pin )-->erasing complete esp flash over power shell command ...esptool_py\2.6.1>esptool --chip esp32 --port com3 erase_flash--> after uploading sketch, same procedure as descripted in "first episode".

Hi Max,

after watching your short video, I guess you made only a minor error.
Please change the setting of your Serial Monitor from "New Line" (Neue Zeile) to "NL + CR" (Sowohl NL als auch CR).

NL+CR.png
New Line plus Carriage Return

Wit this fix the BLE pairing should work fine.
Without this small fix the code was never sent to the camera, that why you received the timeout message.

Good luck!

Hello Chris,

thanks for your replay. Have the same issue as before. If you like in to github repository. --> New Line is written for Serial Monitor. Deeper look into programm code shows:

ch = Serial.read();
if (ch >= '0' && ch <= '9')
{
pinCode = pinCode * 10 + (ch - '0');
Serial.print(ch);
}
} while ((ch != '\n'));


--> char will be read up to \n

Which camera SW version do you use? It is a little bit strange, because I can not connect with any bluetooth app to my camera.

Hi

Few days ago started to write my own Bt library and by surprise found yours - great work!
I did find some issues there, will report them later, also added some additional functionality.

Great project! glad to see you were able to get it up and running on an M5Stack, Very efficient use of the limited screen real estate.

For submitting library modification you should do it via a Pull-request :) ( http://archaeogeek.github.io/foss4gukdo ... quest.html )

Hi,

I have just created a new prototype for my personal use.
Main_Unit.jpg
Main_Unit.jpg (255.41 KiB) Viewed 6136 times


The display is showing and updating:
  • Timecode
  • ISO
  • Codec & Quality
  • Whitebalance
  • Shutter Angle
  • Resolution
  • Tint
  • Shutter Speed
  • Aperture

Functions:
  • Change Aperture via two buttons on the left and right.
  • Toggle recording via long press the middle button.


Use of external hardware:

Use a cheap rotary encoder connected to the grove port on the side.
This dial works as the buttons - but more intuitive.
Full_Set.jpg
Full_Set.jpg (272.28 KiB) Viewed 6136 times


"Special":
Use a micro SD card to log the metadata (e.g. timecode + aperture, shutter, ISO, ...) during recording.
Produce a .srt subtitle file to display in any player or NLE. Still a bit "work in progress".
Main_Card.jpg
Main_Card.jpg (244.99 KiB) Viewed 6136 times


Open topics:
  • Field Pairing without Computer via the Buttons on the device.
  • Make other settings available to change via menu.
  • Detect a disconnect.
  • Automatic reconnect.
  • Long range version via LoRa radio.
  • Simultaneous control of multiple cameras.


Not possible?
Display the battery status of the controller while the grove port (sca & scl) is used for the rotary encoder. (Maybe building a custom connector to use other GPIO pins instead of the grove port.)


Most of the camera code used from Csaba Nagy:
https://github.com/schoolpost/BlueMagic32

Visually inspired by:
https://github.com/IllimarR/BluMagx
(Source code not available, yet?)
& Blackmagic OS...

Hardware:
Board: https://m5stack-store.myshopify.com/col ... opment-kit
Cable / Grove Connector: https://m5stack-store.myshopify.com/col ... rove-cable
Rotary encoder: Bourns PEC11R-4215K-S0024 (maybe)

(+ small case, 3 core shielded cable, 40mm metal potentiometer knob)

What do you think?

Chris

I assembled two devices using the BlueMagic 32 library, everything works, I took the M5StickC and M5Stack platforms. In the beginning there were problems, before loading the sketch, you need to clear the memory, otherwise ESP 32 thinks that BIND is there and nothing happens.

The BluMagx project does not work, white text on a black background, BluMagx tries to connect to the camera and that's it. I cannot clear the memory, BluMagx comes as completely a BIN file.

Hi Wolfgang,

I had the same experience with that fork.
This was the reason to create a sketch on my own.
(based on that library)

Not sure if it has or hasn't been mentioned yet. But if you are having issues getting the initial connection, make sure you are using the older 1.0.4 ( or possibly 1.0.5 ) version of the esp32 Arduino library. They are making changes lately and it is breaking compatibility with Bluemagic32.

But if you are having issues getting the initial connection, make sure you are using the older 1.0.4 ( or possibly 1.0.5 ) version of the esp32 Arduino library. They are making changes lately and it is breaking compatibility with Bluemagic32.

Hi,

the images of Wolfgang are showing that he was using the binary blob file:
https://github.com/IllimarR/BluMagx and not (yet) your great library https://github.com/schoolpost/BlueMagic32.

BTW:
Is it inappropriate to ask for a demo sketch to change the focus (especially for EF-lenses)?
(e.g. via the buttons of the M5-Stick-C or M5 Stack Core)

Chris

Hi everyone and many thanks for your collective effort so far, especially Csaba for taking the time to create this library.

I've had trouble getting this to work and I would greatly appreciate your help on it. My ultimate goal is to use the ESP32 as a bridge between TouchDesigner and the camera. So TD would be communicating with the ESP32 via serial and then using BlueMagic as you all have successfully done. I have been unsuccessful in establishing a bluetooth connection using the library examples though.

My setup is as follows:
-Camera: Pocket Cinema 6K
-Microcontrollers I've tried: M5StickC / ESP32 dev board / Adafruit Feather HUZZAH32
-Arduino IDE

At first I tried with the latest version of the board without any luck and then switched to 1.04

The furthest I can get is inputting the 6 digit pin (tried using newline and both NL&CR) but then the board reboots and the process starts again.

If anyone could provide any help, I would be most grateful.

Has now also happened to me, the BT number is not accepted.
I suspect the camera is no longer able to connect BT. Delete camera BT-memory.

Hey Wolfgang, thanks for replying. Tried clearing bluetooth devices in the camera as well as erasing the esp32's memory and reuploading. No luck sadly. Exact same thing happens. I can establish a bluetooth connection through iOS devices, so I suspect things are OK on the camera side. Did that fix things for you? Please let me know if you found another solution

bad short message:

ESP32 Factory reset (erase flash) is also not a solution.

http://iot-bits.com/erase-esp32-flash-completely/


Code that worked, does not get a connection, camera the reason?

in the next few days I'll get a fresh new ESP32-core2, if it doesn't work either, it's probably because of the camera.


P.S.
with handy-App no problem to connect. camera is ready......

It's running again!

Erase all old Arduino Libary (m5stack, EsP32 etc.) and install brandnew (m5stack + ESP32 only 1.4). thats all.....

only m5stack from here: https://github.com/m5stack/M5StickC

Great to see that my Sketch was human readable (and changeable). :ugeek:

Smaller than expected. Now somehow integrate it into the BlueMagic32 code.

Hi all,

I am working on "field pairing mechanism" to be able to pair or re-pair the camera (e.g. after a reset of the camera) with the controller without a computer.

At the moment I can enter the code via the left button and move to the next digit via the right button.
After all six digits have been set the right button sends the value to the serial monitor as a proof of concept.
Quite simple, yet.
I guess it is harder to makle this work with the library.

As I only need two buttons, this could be easily done with an even smaller device like the M5StickC...

Regards,
Chris
