Hi!
I am using UART in NRF52832 with SDK15.0.0 to communicate with TCP socket via cellular modem.
I am using printf() to send the following AT command sequence to the modem:
AT#SSENDLINE="HiTCPserver|parameter1|parameter2\r\n", and my code apears as:
printf("AT#SSENDLINE=\"HiTCPserver|parameter1|parameter2\r\n\"\r\n");
Please note that the receiving TCP server requires a trailing \r\n included in the message string we put on the socket and that we have escaped the inner "-signs to achieve the proper formatting according to modem AT command manual.
My problem is that printf presents this to the modem / UART, as
AT#SSENDLINE="HiTCPserver|parameter1|parameter2
"
(CR and LF performed)
rather than
AT#SSENDLINE="HiTCPserver|parameter1|parameter2\r\n"
, i.e., the \r\n is included in the formatting already on the UART, rather then being contained and put on the socket.
This results in error message.
When I communicate directly, testpin passthrough debug mode from PC, with Termite terminal ("Append CR-LF" mode) to the modem, it works as expected when I send
AT#SSENDLINE="HiTCPserver|parameter1|parameter2\r\n".
Anyone experienced similar issue?
Thanks and kind regards
