I have enabled flow control on the module and the MCU and now attempting to use a bit rate of 460800.
Both ends are using the right bit rate but only the MCU appears to be controlling an RTS signal. The RTS output
on pin 10 of the module goes low on module initialisation and stays low even when I send a lot of data to the
module. The module is in data mode. Not exactly sure what data is getting lost but the comms protocol between
the MCU and the client (via a websocket) is failing. Using exactly the same hardware and software but a lower
bit rate (115200) works absolutely fine.
Is there anything else I need to do apart from setting console1_hwfc to 1 and turning on RTS/CTS flow control
on the MCU?
