I’ve found what is the problem with Tx fails. When I open the socket I didn’t check if I have errors or not. And I realized that when I open a socket, sometimes (0.1%) I’ve got the error 565, that accordingly to the manual, It is a DNS parse failed:
- Does anyone know if this is a bug?
- Why is it happening?
- Is there anyway to avoid this error?
wrong format QIDNSCFG
snprintf(cmd, sizeof(cmd), “AT+QIDNSCFG=1,”%s","%s"\r\n", dns_1, dns_2);
dns_1 = “126.96.36.199” …
I think I don’t understand what you mean.
I am not using the command: AT+QIDNSCFG. I am using the default DNS. Therefore, I don’t know why I seldom get this error when I try to open the socket. I only get this error around 0.5%-0.1%.
