RN4871 locking up (buffer overflow?) after ~960 characters
This is happening with a RN4871 connected to an MCU, but I've narrowed down and reproduce the problem to an RN4871 on a breakout board connected to a serial terminal (via an FTDI adapter).
Hardware flow control is on (necessary for application).
Shortest path to reproduce it is:
- Enter command mode
- Send commands (I'm using "SHW,0075,1122334455\r")
- Repeat command
After 48 times, the RN4871 stops responding (and the P3_6/RTS line is high).
Doesn't make a difference whether it's connected to a mobile device or not.
I'm using FW v1.30
Am I doing something incorrect here?
