Hi guy, I give a problem with subcriber function MQTT. When i reset a board, it only received some message (from client push auto)
It still publish a message test. ("hello!")
I used code example: mqtt_auth

Hi,
I compile file "example>AIS_4G_board>azutre_IoT>4G>IOT_Central_sample"
But Arduino IDE show compile error as below. Could you help fix error.
Thank you

Hi,
Is there a way to use AT command? I try to upload the certificate and key to SIM7600E module. I connect the cable to female USB-C on 7600 side. When I try to connect via serial, it can't find the port connect to SIM7600.
