UART1 settings via USB



In need to set the baud rate (AT+IPR) and parity etc. (AT+IFC and AT+ICF) of UART1 of a Wavecom Q2686 whilst connected to the USB port.

When I tried it, it did not work. Although the command received a positive response, the actual UART1 baud rate etc. did not change. The AT documentation indicates that these cannot be set using the USB port.

Does anyone know of a way to achieve this? Maybe some Open AT function?



The problem is that AT+IFC and the rest of UART configuring commands must be sent on the specific UART to be configured.
You can build your own AT command, for example AT+UA1IFC. The handler that catch it can resend it to the UART1.


Thanks. I will look into that solution.
