Thanks for confirming that it worked. I don't think super obvious wait_for_flash_ready() can become blocking. You are definitely not the first one to encounter this problem.

Indeed it was this and I'm an idiot for not realising. I moved the check and response into the main loop.

Hi,

Could you try this without calling wait_for_flash_ready() and instead monitor the fstorage callback (or read flash content) to check if data is being successfully written? Not sure if it's relevant to the problem you see, but wait_for_flash_ready() will become blocking if called from an interrupt context with priority 6 or higher because it would prevent Softdevice flash events from getting through (ie the fstorage busy flag will not get cleared).
