@rskoniec Mate I'm paddling hard to keep my head above water with the continual state of pycom/sequans firmware flux without trying to follow up on a single failed piece of hardware. Typical of most hybrids I reckon the RF wafer is probably heaps more fragile than the digital stuff & a glitch down the antenna feedline or on the 5v rail has cooked it. Probably the only disadvantage of having the lte integrated with the smarts on the same board.
