https://devzone.nordicsemi.com/f/nordic-q-a/119236/please-tell-me-how-to-set-the-tx-powerI would like to achieve TX-POWER control using GPIO mode GAIN control on the application core in SDK_VerV2.8.0, similar to how it was done in V2.3.0. Could you please tell me how to set the TX-POWER in SDK_VerV2.8.0?
