RAI feature with LTE-M and MQTT

[Frikkie Badenhorst]

Hi there,

We are currently conducting tests on the nRF9160 using the LTE Serial Modem app. We do however have issues testing the RAI feature on the device with an LTE-M network. The network does indeed support the RAI feature, as we have been able to test this using different devices.

According to the AT commands reference manual, the %XRAI command is not supported in a LTE-M network? Is that indeed the case?

We then refer to the %RAI (8.17 in AT commands reference manual) and %REL14FEAT (8.18). However, we are not able to use any of these 2 features? We continuously get the "ERROR" response when trying to active the REL 14 features. We have set CFUN to 0,1 and 4 to attempt this. 

Can you please assist with instructions on how to enable this feature on a LTE-M network so that we can test it? 

This is very urgent as we need to decide on which hardware we will use in our product today/Monday.

Hello Frikkie,

We are coming back to you as fast as possible, but you have to expect some waiting time! We are not always able to provide an answer immediately, especially not during the summer vacation period.

Thanks for understanding!
