3 years ago If everything works when it's plugged in to USB but not battery, it's probably a hardware problem related to whatever voltage regulator feeds power from the battery to the SIM7000. I don't know anything about that specific board, but I do know that if the SIM7000 isn't getting enough power it won't work. It might be able to communicate over the serial port but it won't connect to the internet. You'll have to take a hard look at the schematic and look at what regulators are feeding power where and how much load (amperage) they can handle. You might need a secondary battery or something. I suggest you look for help on the site or forum of whoever manufactured your board.
If you have a software issue with the library, please make a new issue for it!
When I am with the serial connexion everything work but on battery I haven't the return on dweet (with SSL). I haven't Solar panel, I dont know if it is the problem. The battery test is ok (64%, 3,84V) I haven't test because I haven't serial return. Sorry for my english, I'm french. Thank for your help
