I would like to read the Tx power level from the modem module (LE910-NA1). Base on the AT command guide, there is a AT command (AT#RFSTS) that will report the . However, when I type it in, the command always reports TXPwr of 0.
The document indicates that it’s for “In traffic only”. I am wondering what that means? I tried to set up a data call and issue the RFSTS and I still get 0 for TxPwr.
What do I need to do to enable the TxPwr reporting?
Response that I got from the module:
#RFSTS: “302 610″,925,-113,-77,-15.0,2bdc,FF,0,0,19,1,”1BA2B2A”,”302610016730170″,”Bell”,3,2
Can you please confirm that you are usng the firmware release of 20.00.522 on your LE910-NA1? The note of “In traffic only” for the TXPWR parameter relates to that parameter will only be present/populated during an active transmission of data (traffic). Your result from the #RFSTS command shows that the module is Idle (19) by looking at the MM parameter. I would expect the MM value to be a 6 or 21 before you would see the TXPWR parameter populate, since that would be an indication that your connection is active.
Please contact TS-Americas@telit.com if you need to get the latest approved firmware release for the LE910-NA1.
Thanks for your response. I am using the 20.00.522 firmware.
A data connection was set up and I was doing a ping test at the background when I send the RFSTS command. Do you think that’s sufficicent for the RFSTS to report the TxPwr?
If not, can you suggest a better test setup?
I would recommend doing a test that could take longer on the transmit side to complete, maybe an upload of a file via a FTP or PPP connection. From my short testing I am seeing the same results when doing Ping tests, I have not been able to catch the MM parameter to be an 6 or 21 during Ping testing.
