Set Tx Power on nrf9160

lorv

Hi,

I'm currently making energy measurments with an nrf9160 DK. The software project is based on the udp_with_psm sample. I would like to run the test on different tx-power levels.

I have seen that the tx power can be adapted with the AT%XRFTEST, but is there a way to set it permanently? Preferably with a define that can be added to the proj.conf file? Or is there an AT-command to set the tx-power level?

    Hi,

     

    There is no way to change or limit the output power manually on the nRF9160. The cell tower will drive this communication, and tell you to use a lower output power setting if the link budget is good when communicating with it.

    %XRFTEST is a RF test mode, where it can be set in different modes; but be sure to test this in a RF-chamber, as you're dealing with licensed bands.

     

    Kind regards,

    Håkon
