Understood tx operation...

I previously try set_TX_power call alone.

Because of i am not staring the advt init function before tx set call so it is hang issue was there.

Now code is working properly....

Thanks for your support...

Hi Kenneth,

Please check this below images ....I am getting following error..What that error means?

this error is after calling tx_power_set(); in main (Withot read write function) and declare "uint8_t TX_POWER_LEVEL = (4) ; //default"

What modification is required?

Waiting for your reply....

Okay..

Because I have implemented read write for other two-three data like advertising interval. That is working properly.

It is properly reading updating data from flash so what is the issue , i am not getting...

You need to debug this somehow, my suggestion for instance is that remove flash writing, custom characteristic and system reset for now, and simply call sd_ble_gap_tx_power_set() to see if it returns any error code after a connection is established. If there is no error code, then the issue must be somewhere else (custom characteristic or flash writing). It should not be required to reset the chip to change the output power.
