EC200T and USB HUB

IoT Modules LTE Standard Module

Good day

I’m experiencing a strange issue. We have an EC200T USB module connected to a USB hub (Microchip USB2514BI-AEZG)

Whenever the SIMcard data depletes, the HUB resets and the driver looses connection to all the other connected components. Any ideas or suggestions?

What changes on the GSM module whenever the SIM depletes?

Thanks!

Hi
You can do an exception handling mechanism to restart the module when SIM depletes are detected.
