I am trying to use the AT command mode that is pre-loaded into the mdot using a USB to TTL cable connected to my computer. I am using a Usart Terminal program.
The cable is wired to the mdot Din and Dout lines.
Any At command I send, the mdot just echoes back what I have sent it. Are there any other signal lines I need to tie high or low to get this to work?
Any help would be greatly appreciated.
