This error message is only triggered if the BLE module on the microcontroller is not running smoothly or if the connection is lost at a very specific moment. I wonder if the load while transferring the file is higher than sending data…I tried with iPad, now i ask my collegue to try with iphone. I have 5 custom devices and 2 dev kits i'll try to repeat test with all of them.
- Is there any chance that you could try an iDevice or a Mac with Apple Silicon in order to check if these also fail?
- Could you test it with more than one C3-MINI? We once had a DevKit shipment that got broken BLE modules…
- Do you observe data loss compared to the S3 if you use the S3 experiment? (Also try to increase the rate and check if this also leads to problems with the C3.)
I check back with our hardware expert if he has any additional idea what could go wrong or how you could “optimise” BLE reception. Unfortunately, we do not have any of these he
( we are a small company in Italy and we produce physics experiments, we made a smart Wilberforce Pendulum, actually it interacts with other software smoothly but the idea that everyone could make a basic data acquisiton with Phyphox it looked interesting for us)
At moment we have a S3 controlled IMU and a C3 controlled IMU. The only difference was related to board size because with C3 we can fit everithing in a smaller area.
I'll try to check the 3 points you suggested and eventually come back. Thanks for your support.
