ATCmdParser doesn't work

Hi,

I used below code to communicate with GPRS module by using ATCmdParser, but it doesn't work, can you help to comment?

platform: NUCLEO F412ZG

AT UART: UART 1

UARTSerial test_serial = UARTSerial(PA_9, PA_10, 9600);

ATCmdParser at = ATCmdParser(&test_serial, "\r\n");

at.send("AT") && at.recv("OK");

at.send("AT+CWMODE=%d", 3) && at.recv("OK");

at.send("AT+CWMODE?") && at.recv("+CWMODE:%d\r\nOK", &value);

looks like it was blocked in receive data.

update: I add log in the receive function, I can get the raw data from getc(); but at last it return fail. maybe because the data input format is wrong? any user guide for ATCmdParser?

I think that you need to do:

at.send("AT+CWMODE?") && at.recv("+CWMODE:%d", &value) && at.recv("OK");

As the \r\n is the delimiter character and thus shouldn't be in the recv() command. This is how we do it in the esp8266 driver at least.
