I think this firmware was recently released and is still in testing. Maybe in the future, you'll be able to download it directly from nRF Cloud.

Where does the "">firmware.nrfcloud.com/.../mfw_nrf93m1_update_from_1.4.1_to_1.5.0.bin" address come from?
Obviously that is correct for that exact diff, but where should users go to find the appropriate file for future upgrades?

Hi,

Please take a look at the following: Extended signal quality +CESQ • nRF93M1 Cellular AT Commands • Technical Documentation
The 3GPP standard AT+CESQ can be used.

> at+cesq
 
+CESQ: 99,99,255,255,30,70
 
OK

Please let us know if you have any further questions.

Best Regards,

Hello,

Thank you for your information. I successfully updated the firmware to version 1.5.0.

However, I have another question. In standard 3GPP modems, the AT+CSQ command typically returns a signal quality value ranging from 0-31 or 99. On the nRF93M1, the behavior appears to be different.

Could you please advise how to obtain the equivalent signal quality information on the nRF93M1, similar to the result provided by the AT+CSQ command on standard 3GPP modems?

Thank you in advance for your support.

Best regards,

Hello,

I would recommend you to update the modem firmware version to 1.5.0 using HTTP download. You can take a look at the following example to update mFW with base version 1.4.1 to 1.5.0:

 AT%HTTPFOTADL="http://firmware.nrfcloud.com/93m1/mfw_nrf93m1_update_from_1.4.1_to_1.5.0.bin",100

The command is :

%HTTPFOTADL=<HTTP_URL>[,<download_URC_max>]

Let me know if you have any further questions.

Best Regards,
