Hi, I am currently using the hologram sim card in singapore using Sara r422s. I am having an issue with hologram sim card. I can see that the hologram will use CAT-M1 and connect to singtel
Connecting to the cellular is all fine, I can get an ip address and rssi without any issue. However, whenever i make a connection to the mqtt broker. The cellular network will disconnect and reconnect immediately. Is there anything i am missing? I don’t see this issue using other providers sim card in singapore though.
This happens intermittently. Sometimes after the device is connected to the cellular and broker, i will get a disconnect to the cellular. Subsequently the same issue will happen again.
Regards,
