Hi Kenneth,

Thanks for your reply.

[quote userid="2111" url="~/f/nordic-q-a/60574/send-tx-power-in-advertising-packet/246239"]However it make sense to call it before you start advertisement.[/quote]

Is there a way by which I can update the advt. packet to transmit the power level without starting and stopping the advertisement?

I mean in my application, I change the transmit power as needed but everytime restarting the advertisement is not feasible.

How can I update .advdata.p_tx_power_level to show the change in power in advt. packet?

Hi,

There is not direct dependency between when you set .advdata.p_tx_power_level and call sd_ble_gap_tx_power_set(). It is in theory possible to dynamically change the output power at any time by calling sd_ble_gap_tx_power_set(). However it make sense to call it before you start advertisement.

Best regards,
Kenneth
