HL7810 vs HL7800 AT Commands. HL7810 AT+CDGCONT=? never returns OK

IoT Modules HL78
1

I am currently trying to implement a HL7810 modem into a linux system that has been using the HL7800.

A number of AT commands which worked for the HL7800 now fail with the HL7810 with identical AT+KUSBCOMP configuration. The first key command that fails is AT+CGDCONT=?. In order to confirm that the issue is not due to the linux system I placed both modules in the Sierra Wireless dev board and communicated with the modules over a putty serial connection.

HL7800:

HL7800.4.4.6.0

As you can see this command never returns OK.

There are now avaulable firmware updates for the HL7810 that I am aware of.

Any assistance on the issue is appreciated.

Thanks

Hi @peter.bouvy ,

So, if the “OK” is not returned, it should be the issue, please raise ticket with Sierra Wireless via link https://www.sierrawireless.com/support/ for more support.

Thanks.
