I'm a student who is trying to make a simple project with arduino and a sim800l evb module.
I watched some videos on youtube to hunderstand the basic but i'm stuck cause my sim800l doesn't work.
I can't figure out wich is the ring of the chain that doesn't work, it could be a wrong supply or wiring, defective board, wrong sim plan or maybe the code; so i'm here to ask help.
The only things that i can see are:
- the module's leds doesn't light up
- the module heat up a little bit
- if i give some at commands form serial monitor it does noting
This is what i have:
- Arduino uno
- Sim800L EVB
- Powerbank 5V/3.4A
- sim form thingsmobile
This is the wiring (board -> arduino):
- 5VIN -> Powerbank
- GND -> Powerbank
- VDD -> 5V
- TXD -> pin 2
- RXD -> pin 3
- GND -> GND
- RST -> X
The tutorial video that i used is this: Impostare il modulo GSM SIM800L per utilizzarlo con Arduino - Video 563 - YouTube
It is an italian maker (i'm also italian) and it is pretty reliable, is not the first time that i use one of his video like reference.
If you need further informations tell me
Thank to everyone
