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?
