when i connect NRF9160-DK to the CMW 500 for CAT-M test, the NFR9160 can register with CMW500, but the connect drop very quickly,

[chengfeng.zhang]

when i connect NRF9160-DK (version 0.8.5 )to the CMW500 for CAT-M test, we have send the below three commands

AT+CFUN=4
AT%XSYSTEMMODE=1,0,0,0
AT+CFUN=1 to 

the NFR9160 can register with CMW500, but the connect drop very quickly, and this issue can repeat.

he CMW500 connect screen as the attached file, please help to analyze

At the same time, connect NRF9160-DK to the CMW 500 for NB test is normal, we have send the below three commands

AT+CFUN=4
AT%XSYSTEMMODE=0,1,0,0
AT+CFUN=1

the NFR9160 can connect to the CMW500 well, and the performance is normally;

by the way , we use CMW500 to test the other company CATM sample，it can also connect correctly;

Hi,

 

Could you flash the at_client, and use nRF connect for desktop, application LTE Link Monitor when connecting? This will also enable network related error codes etc in the initial setup, which can give more information on why its not connecting properly.

 

Kind regards,

Håkon

Is the NRF connect is free，if it is free, show the provide official free statement link. you know, before we install the software,we need to know if it is free and legal;

second updated the CMW information, when connect fail, the cmw 500 show signaling failure.

Hi,

 

nRF connect for desktop is a program that we provide. The license on the open source parts are included here:

https://github.com/NordicSemiconductor/pc-nrfconnect-launcher/blob/master/LICENSE

 

Kind regards,

Håkon

[chengfeng.zhang]

the license on https://github.com/NordicSemiconductor/pc-nrfconnect-launcher/blob/master/LICENSE is related to the NRF connect 3.70, 

if the “LTE Link Monitor” in NRF connect 3.70 is free for business use for flex ？

[Håkon Alseth]

Hi,

 

Yes, it is:

[chengfeng.zhang]

Remove the PRC connection, as https://devzone.nordicsemi.com/nordic/cellular-iot-guides/b/hardware-design/posts/using-nrf9160-against-r-s-cmw500-or-cmw290-in-signalling-callbox-mode shown,

the CM500 can attached to the nRF9160, but touch the connect button, it can not build connection.

[Håkon Alseth]

Hi,

 

The difference that I see is the half-duplex being enabled. Sorry for missing this in your initial configuration setting. This must be enabled with the nRF9160, as it is half-duplex only.

 

Kind regards,

Håkon
