Known failures and troubleshooting
- Undervoltage during burst transmission is the classic reset cause — budget 2 A of headroom on the supply.
- The USB interface enumerates several functions; identify the AT port before configuring the application.
- Firmware variant (CE, CE-H and others) changes band support — confirm the exact suffix before ordering.
