I am currently working on a project using the almost-dead board Lightblue Bean+
It consists in an 328P connected with an Bluetooth SoC.
I was programming sketches, when suddenly my sketches stop running. I have done tons of debugging, which include:
- Resetting the SoC
- Resetting the 328p
- Rewriting the Firmware (I think it rewrites both bootloaders, from the SOC and 328P, but I am not sure)
- Checking power needs
- Tried to deactivate Watchdog timer (followed 328P users manual)
- and other things related to the LIGHTBLUE BEAN and not just the ARDUINO.
Anyway I really think that the problem is mainly on the Arduino side.
The port D9 is stuck at HIGH, while the D8 is at high but not as much (sorry, I currently have no way of measuring it, but an LED connected to it lights ''halfway'')
I would like any help on how to continue to debug it.
