nRF5340 BLE transmit power

[WilsonChen]

Hi Sirs,

in nRF5340, is it doable for  to adjust the power index of different channels of BLE_1M or 2M, in terms of SW code  (if there is then where? or NVRAM like setting (read-out/modify/fill back, and effective right after re-power on and won't vanish from then on until change setting doing agin?

Also it is not doable to change the power index via HCI command dynamiclly druing the test?

Thanks

Hi Oivind,

Thanks and we are looking forward your input

In temrs of BLE certificate for FCC, we need to know the exact capability of different channel setting with different power index.

Per MPSL it mentioons: The current implementation of the FEM support does not implement the SPI interface or MODE pin support and does not change the transmission power after the initialization. Does it mean MPSL is one-time programming or the library/data can be stored in NVM or flash and edited then fill back?

Thanks,

Wilson
