https://devzone.nordicsemi.com/f/nordic-q-a/126324/what-is-the-speed-of-updating-txpHi I am wondering when I use this function, how much time do I need between I set a TXP and a TXP has been successfully updated. I am developing an application that needs to quickly change the TXP, maybe 5 times per second.

You can use&nbsp;hci_vs_sdc_zephyr_read_tx_power() if you want to read back the current TXPOWER configuration. And if you have a PPK2, you can verify based on the peak current whether your TX power updates are applied in time.</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
