Electron flashing green for 10min then blue

Hello, My electron was running for about 2 days without a probelm. But since yesterday it isnt able to connect to a cell tower. It flashes green for 10min and then blue. Since i didnt changed anything in the Code does this mean i have a problem with my provider(t-mobile)?

Is it a Particle SIM card?

You can follow the steps here: https://docs.google.com/document/d/1NdYxPPk_i_mM2wM9oSbSZB1ElDlHA_x-IHY-UC7w62M/edit

and paste the output for us to see what’s going on :slight_smile:

Thank you for your help. I am using a 3rd party sim. This debugging app wont work with a 3rd party or?

The debug app is generic and should work with any sim.

Since you are using a 3rd party sim, did you make sure the keepalive is set appropriately?

ahhh this can be. This is the first time I hear about the keepalive. So this might be the problem. Can you explain what I have to set and how ?


@kennethlimcp thank you for your help, but I was able to track down the problem. (It wastn the keep alive) I am powering the electron with 4AAs through VIN. When I power the electron with the LiPo it works without a problem. With the 4AAs the electron flashes grey for 1min then blue.
Does that mean that the Power of my AAs got to low ? They got pretty low but they are still providing 4,7V which shoudl be enough ?!
