Output power using ESB with '840

Hi Andy, glad to hear you got it working. The library was designed in a pretty bare bones way, so that's why it doesn't include every possible TX power define in the header file.

Best regards,

Simon

Thanks Simon,

I see that you can just input an arbitrary int8 for tx power. The examples still use ESB_TX_POWER_NEG20DBM etc. from esb.h which does not contain a ESB_TX_POWER_8DBM definition, but if you just pass a raw int8 it works as expected.

Hi Andy

This seems like a documentation bug, and not something in the SDK. As of NCS v2.2.0 the TX power was changed to be an int8, so you should be able to set the TX power to whatever you'd like. +8dBm was never actually implemented in ESB on NCS, but should be possible to set if required.

Best regards,

Simon

Hi Simon,

It seems this is still a bug as of nrf connect sdk 2.3.0? Is this correct?

Hi Henry

It seems you found a bug in the SDK, Nice catch! It should not be a problem setting the RF output power to +8dBm. You can either implement it into the nrf_esb.h file yourself with something like:

NRF_ESB_TX_POWER_8DBM = RADIO_TXPOWER_TXPOWER_Pos8dBm, or you can just add RADIO_TXPOWER_TXPOWER_Pos8dBm directly to your project's main file.

I've reported this internally, and it should be fixed in a future SDK release. Stay tuned!

Best regards,

Simon
