In my Previous topic i posted about a wifi issue that occurs randomly with reset. I tried all the workarounds posted by other members, like staggering the timers, testing individual functions but no luck. It always ended with an exception. Today i found out a way to decode those exceptions using a tool called exception decoder
Exception 29: StoreProhibited: A store referenced a page mapped with an attribute that does not permit stores

Has anyone experienced this exception before??. its related to Blynk connect or wifi as my board tries to connect to blynk server several times until it uses all its heap memory and then resets. Can any one point me in the right direction atleast. i am stuck with this issue.
@Dmitriy maybe the founders can shed some light on this as why this might happen. Any help will be appreciated.
