central and peripheral communication

[karthikeyan]

hi support team, my nrf52840 is acting as peripheral and my mobile with nrf connect is acting as central. after the connection i am able to read and write my device name, link loss alert, battery notification alerts, immediate alert by using my nrf connect app with necessary changes in my program. my doubt is i have given read write permission to tx power by these changes..

but in nrf connect app i can only able to read the tx power. i cannot able to write it. do i want to make any other changes or the nrf connect app is developed in the way that is only able to read tx power not to write. can anybody solve my doubt?

The Tx Power Level characteristic value should per spec not be writable, see this.

If you want to go out of spec, you can add

char_md.char_props.write  = 1;

in tx_power_level_char_add().
