Hello,
I am currently developing a project using the nRF 9151 and SDK version v2.7.0.
The issue I am facing is that I have configured the PSM mode, but it doesn't seem to take effect.
I used the command AT+CPSMS=1,,,"00000101","00100010" for configuration, and the response was OK.
Then I sent AT+CPSMS? to query the configuration, and the response was +CPSMS: 1,,,"00000101","00100010" OK.
After that, I sent AT+CEREG? to check the registration status, and the response was +CEREG: 5,1,"1D39","054038BD",9,,,"00100010","11100000" OK.
From this response, it seems that the TAU cycle was not successfully configured.
Moreover, I used a power analyzer to check the power consumption, but there was no noticeable change in power usage, which confirms that the device has not entered PSM mode.
What do you think could be the reason for this issue?
Best regards,
