I am using OpenThread network and working on CoAP Client and Server examples (Customized). Everything working fine when devices are on main power.
My client devices are FTD and once I connect them on Battery, they work for some time (1 or 2 hour) and stops communicating. The only thing which works is Hard Power reboot (disconnecting Battery and reconnecting main Power). Upon checking, Battery still has lot of power and there was no sudden or new data flow. Same battery can be again used and again it works for 1-2 hours.
Unfortuunately, since these are CoAP-Client devices, I am not able to give any command also to them (if some one can suggest).
Please help.
