I m working on a custom board based on DA14681. I m working on that board for over an year and it worked fine. But now when i perform a SUOTA update, at 1st it used to connect and suddenly disconnects and DA14681 restarts.
This was happening with my Firmware that was in this month. Binaries of old firmares were working fine that were 5 6 months old firmwares.
So then i disabled the watchdog and now when SUOTA update is going on, it didnt disconnect but it freezes at 0% even for 45 minutes.
I m not able to find what is the problem and what have i done in the code that this is happening. cz last 6 monhts old binries are find but last one month are not.
Please help me.
