I have quite a problem with powering my SIM800L EVB like this one: link
The module keeps on resetting every couple seconds. I’m powering it with a 12V 5A wall adapter through LM2596 (The board should be powered with 5V). I also added 4700uF cap as you can see on the picture below. I can use AT commands but when I want to check AT+CREG all I get is +CREG: 0,2. Any help would be much appreciated.
I’ll give it a try then. I will let you know how it went later. Thanks for the quick response.
UPDATE: That was it! I can’t stress enough how much I’m thankful for your help. After so many hours of trying different things it finally started working. Thank you for your time! All the best ALEXIS!
Thanks for helping out @ALEXIS You are the best @szakala The capacitor needs to be close enough to VBAT pins for delivering the surge current needed. Alexis was spot on.
