@Rasyid Do you have a valid network connection ?
For Quectel BG96 you can verify the network connection with the following AT commands
AT+CGPADDR //check IP address AT+CGATT? //check if attached to network AT+COPS? //check current set MNO AT+COPS=? //scan network for mobile operators AT+CGDCONT? //check APN AT+QPING=1,"172.27.131.100" //ping UDP serverRegards, Roland
