Hello, i figured out why modem could not connect. The reason is that AT+NETOPEN should be called as AT+NETOPEN ,,1 But here's another problem now. I get bad request from server now.

I create request is this way: http.get(url);

  http.sendHeader("firmware-ver", FIRMWARE_VER);
  http.sendHeader("Authorization", basicAuthStringB64.c_str());
  http.sendHeader("Content-length", 0);
  http.sendHeader("Content-Type", "text/plain");

  http.endRequest();

Here is AT debug code:

OK AT+CIPSEND=1,12 AT+CIPSEND=1,12

firmware-verfirmware-ver OK

+CIPSEND: 12,12 AT+CIPSEND=1,2 AT+CIPSEND=1,2

: : OK
