Hello All,
I have nrf52810 chip. using softdevice 6.1.1
I have implemented dfu feature.
Now i have implement tx power change feature through nrf connect mobile app using custom service .
I am saving the variable in flash after receive from app but code is freezing there while setting tx power.
Device is not advertising , its hanging there..
So i have try to use NVIC_systemReset() , but after reset my all buffer are resetting . After that am reading saved data from the flash but it is not reading new data ,
It is taking default data that set while initializing code at the start.
for this tx power change Is reset is required to set updated tx pwer value?
If yes then which reset should i use ? Is there any soft reset?
Please check my code for tx power change below and provide your input.
