Is there an update for this topic? I’ve read threads from as far back as 2015, the most recent ones are inconclusive. I want to wake up an Electron with an SMS or interrupt pin.
Basically, it’s an asset tracker that I want to check in on remotely but when the device is powered up or moves, I want to know about it. I’m using an ADXL362 sensor OR’d with a signal from the 3.3v power supply. I’m open to hardware ideas at this point, the PCB is not finalized so things can change.
I’ve read that it should wake up from any EXTI, but that is not the case. Only the interrupt pin specified in sleep does the job.
I’ve tried the WK pin in sleep mode, thinking it was a default wake pin at the hardware level, but it doesn’t wake the Electron from sleep when it’s not the one specified in sleep(). Am I missing something here?
I have already reduced two possible EXTI’s on my PCB into one, but the problem now is that I can’t do the same with the ring indicator, since I understand it’s not accessible or I would just solder a jumper.
@mdma had a post saying it was in the works, but I can’t find any updates since that post.
Thanks everybody! This is the last hurdle for my project.
