Hi,
1. I added an at instruction to the example serial_lte_modem to connect to the nRF Cloud but it always fails. What can I do?
2. The code is as follows:
7077.serial_lte_modem_ag3352.zip
3. Connection logs are as follows:

4.In addition, the device automatically restarts at the end of the log. How can I solve the restart problem?
5. Based on the example serial_lte_modem_, the following modifications are made:
(1) Set the network mode to NB
(2) Added an AT trigger instruction AT#XPTGPS=1,2,3,4,5,6,7
6.Test board: PCA10090 1.0.0 sdk:NCS V2.5.0
7.Send instructions AT#XNRFCLOUD=1 in the LTE Link Monitor
You can connect to the nRF Cloud
Need to pay attention to the file and location
Thank you for all your assistance.
Kind regards,
Peter.Min
