I am working with bg96 communicating with MQTT. When I use GSM network to connect to MQTT it works fine. But when switching to NBIOT network, it leads to “Fail to parse domain name” error. Has anyone encountered this error? Below is my program.
I have the same problem with my BG96, I can use MQTT with LTE-M but when I switch with NB-IoT I can not use MQTT. In fact, the problem is that the the low native speed of NB-IoT does not allow TCP/IP in many situations.
