RE: Flash Write in BLE event

is there any other way? to use flag?

in code, main loop is just execute nrf_pwr_mgmt_run();

other things execute when interrupt is happend

if flag input the main loop, it works very well. however I think it is like polling. it is not nice code.

like register event handler and and so on..

Hello,

[quote user=""]I thought that use callback or other event handler, escape ble event, and try flash write.[/quote]

That sounds like a good plan.

Maybe you call the flash write function inside a BLE event? If so, try to set a flag, and call the flash write in the main context (from your main-loop). That should allow for the flash operation to start, something it wouldn't if you try to call it from the BLE event handler.

Then remember to wait for the flash event handler before you try to read the flash again, to ensure that the write is complete before you try to read it.

I would recommend to use the FDS library.

Are you sure you want to write the data to the UICR area? Is there any particular reason for this? I believe this has restricted access while the softdevice is running. In addition, it is not that easy to update the value you store here. It is intended to only write to once, and then leave it for the lifetime of the product. That is why you should use the "normal" flash, which it will use if you use FDS.

Best regards,

Edvin
