Hi, I am trying to connect my sim800l module to the sim network. I am using an Iliiad sim without pin.
I know that with this module there is a big problem with the alimentation because the module needs 2-3 A sometimes. I recently watched a cideo on youtube and the guy used a lipo battery 18650 like the batteries at this link that I purchased: 4 BATTERIE BATTERIA RICARICABILE IONI DI LITIO 8800 mAh 3.7V BL-18650 TORCE LED .
I still can't connect to the network (because it should blink every 3 seconds instead of every second) but I don't understand the cause, it could be :
- the battery that doesn't supply enough electric current;
- the adaptor of the sim that I used (I put a picture down below);
- some problems with the module that maybe is defective.
could someone send me a battery or a combination of elmenets that assure me that the energy supply will work 100% or tall me if the battery that I use is not the problem?
Here are some photos:
