I am working on new design using the WS6318 and microchip PIC32MX250F128D (using IRQ on RX and TX)
I got my AT commands working nicely
but as soon as I send ATE0 I loose comms with the GSM module.
if I replace it with ATE1 then it is fine and all works (any at command works as replacement)
I have tried my comms with Flow control on and off and no difference
And if I create app that just take USB data and pass it to GSM and vice versa then ATE0(when sent manually) works as it should and nothing breaks.
So only if my micro sends the “ATE0\r\n” at 115200 baudrate does it break.
This is very strange
Has anybody seen this?
