I am using SIM800 with STM32F0 in a project. I am using UART protocol for communication between them. After sending the AT-COMMAND and I am waiting for response, I got both (AT-CMD + RESP) Example:
sent: AT+FSLS=C:\ \r\n
resp: AT+FSLS=E:\ \r\n file.txt \r\n
In all application notes and in the response buffer, we just get the response like this:
sent: AT+FSLS=C:\ \r\n
resp: \r\n file.txt \r\n
Any hint?
