if i adjust the tx power of nRF52832,which phase of the current will be affected?

Dear friends,

    if i adjust the tx power of nRF52832, e.g., by calling sd_ble_gap_tx_power_set(), which phase of the current will be affected in the pic bellow? just the phase (G)?

If so, how can i get the relationship between the current and the tx power? p.s,  (E) for Radio RX, (G) for Radio TX.

Easiest way is to enable radio notifications and in the interrupt handler you can toggle GPIO to indicate tx or rx activity based on the radio events. All the radio events are well documented in the manual.

Or, you can use ppi/gpiote to fork off the events and drive gpio directly.

Or, you can use pa/lna assist in the SD to drive gpio.

There you go. Three easy ways to give you tx and rx indications on any design.
