I have been using a Electron for a while… Well up to my third where by they are generating a SOS Hard fault code when a text message is received. I downgraded, flashed tinker, upgraded and re-flashed a working version of my code I know that works, and have been running on other Electrons for the last few months but same thing happens, On sending it a SMS I get a hard fault. They can connect to the server, send messages and work fine other hen the hard fault.
The code I am using is https://github.com/CameronTurner/Particle_SMS_Send_Read, is there any known way of making them like factory again? other then the methods I have tried above?
