I want to change Tx Power while connected

[sdi_kei]

Hello.
I am developing using nrf52832 (S132 v7.0.1, SDK v16.0.0) as central.

Is it possible to change the Tx Power while connected to the device?
I made it possible to change from -20 to 4 using "sd_ble_gap_tx_power_set", but I felt that the connectable distance did not change.
Also, the value of the register (0x50C) did not change when I called "sd_ble_gap_tx_power_set".

Thank you.

Hi

Please check out this case, which explains how to use the sd_ble_gap_tx_power set() in detail, and how you can change the TX power after you've connected to a central. What is the peripheral in question here btw? It is important that the peripheral supports changing the TX power as well.

Best regards,

Simon

EDIT: Very sorry, the link didn't seem to be added.

Hello.

Could you give me a link to the case?
I am using an Android device (Bluetooth 4.2, Android 8.0.0) as a peripheral device.

Thank you.

Hello.

In other words, is it okay to change tx power as many times as you like by calling "sd_ble_gap_tx_power_set" while connected?
And what if the advertised tx power doesn't change?

Thank you.

Hi

Due to the summer vacation period we are currently understaffed, so delayed replies must be expected. I am sorry about any inconvenience this might cause.

Yes, that should be fine. What do you mean about "if the advertised TX power doesn't change"?
