case about nRF9160 CMW500 test Can't identify

peter.min

Hi

1.Referring to this tutorial, the customer tested the cat-m mode, and the equipment could not be identified by the customer instrument. How to deal with it?

 Using nRF9160 against R&S CMW500 (or CMW290) in signalling callbox mode 

2.nRF9160

sdk :ncs v2.1.2 

example  :serial_lte_modem

modem :mfw_nrf9160_1.3.2.zip

3.

Customer instrument model: CMW500

Customer instrument version: V3.7.42

Thank you for all your assistance.
Kind regards,
Peter.Min

    Hi Peter.Min,


    Is that configuration file (M1_configuration file for signalling.zip), which can be found at the end of the thread you mentioned, definitely installed on the CMW500 tester?

    If so, would it be possible to program an AT Client sample into the nRF9160. And after that, with LTE Link Monitor, enter the AT commands:

     AT+CFUN=4                              // to set the device to flight mode
     AT%XSYSTEMMODE=1,0,0,0        // to enable LTE-M1 mode
     AT+CFUN=1                              // to set the device to full functionality

    In this way we were able to establish a connection between the nRF9160 and the CMW500.


    I understand that you want to use the Serial LTE Modem example, but at least this way you could rule out hardware failures. Then it would be easier to find out if your application program requires changes.

    Best regards,
