@Bdub Have you heard about any issues with Electrons that are outside having connectivity issues due to the SIM card holder possibly flexing or contracting from the constant temp changes? I’ve had a unit outside solar charging but eventually it stops connecting and sending data even with a full ba…

This is the first I’m hearing of this. Usually with SIM connectivity issues the unit will drop off the network and be blinking dark blue (in Listening Mode). Without touching the SIM, if you remove power and reapply it, the electron should go to blinking dark blue if the SIM has a bad connection.

@BDub I never saw the Blinking Dark Blue, but I never pulled the battery connector out of the battery JST connector jack either. I’ll remember to verify the bad SIM card connection by pulling the battery and looking for the dark blue LED indicator. Stay Tuned… It’s been in the -2 - 20F temp range…

@RWB , I guess this is going the same way as this thread, isn't it? [image] Industrial grade electron possible in the future? Hardware @zach , @zachary , @mdma , The electron is great for building remote, configuration less devices. At present the operating temperature of the…

@RWB , @ScruffR , This seems indeed be more than the same direction. I think there is a big need for an extended temperature range Electron. I use iot sim cards from a local Belgian provider and these are all -40C --> +85C for these purposes, so there are solutions for this. The biggest concerns are t…

I think the Electron as it is now is perfectly fine IF the SIM card socket does not start causing issues due to wide temperature changes over the seasons. I’m planning on building an add-on shield for the Electron to add a new battery management chip that has a better fuel gauge and support for the…

@RWB , thank you for your response. Your comments on the battery component are very interesting! And indeed the shield your are talking about would be very good. However is Particle is going to make a new version of it, they might as well integrate this as well. It might be worth to contact @will for…

Hey folks – as we’ve continued to investigate an Industrial variant of the Electron, extended temperature ranges and SIM reliability are two issues that have been front of mind. I’m hoping that we’ll be able to address both of those concerns with a future hardware release. It’s still too early in p…

@BDub I’m having issues with the Electron not reconnecting or reaching Cellular.ready() after the Electron has been in deep sleep mode for a few days of bad weather. So the SOC stays below 20% for 2+ Days while the Electron wakes up every hour to check if the SOC has risen above 20% and it can do t…

If you are waking up from deep sleep: else { Cellular.on(); delay(10000); Cellular.command("AT+CPWROFF\r\n"); delay(2000); ... Then I’d say that should be equivalent to pressing reset. Pressing the RESET button does not however reset the cellular modem. Those are decoupled speci…

@Bdub Sweet! I just added the Modem Reset code to run only if the Cellular.connect(); > Cellular.ready(); = True does not happen after 5 mins of trying. I’m going to try this and see if it makes any difference or not.
