I’ve been using the modem with the following board (https://www.sparkfun.com/products/13263) and it often works, but after several connect and disconnects (when developing) suddenly stops working and I get a timeout/error. Then i’m no longer able to reestablish connection with the modem.
For fixing this i’ve tried:
-Reseting the computer/ports
-Changing the USB
-modem.send_reset()
The only workaround so far has been a power reset. However when deployed this will not be possible. Any suggestions?
