Hi to all,
I have SIM800L module and D1 mini microcontroller with Micropython firmware...
Can those modules connect themselves and how? I would like to send SMS. I take SIM from my telecom provider...
Does anyone know good python script that works out of the box with those modules together? Some good links? I found couple of links but for ESP32 or Arduino or something other but I have those two modules and like to do this with micropython...
Thanx in advance,
Jadro

Re: GSM SIM800L
You do have 2G support still in your country?
What is a D1?

Yes I do have, 2G , 3G... and D1 mini is ESP8266 based microcontroller, Wemos D1 mini, it is on the picture I uploaded, It has Txd and Rxd pins
Re: GSM SIM800L
Will you have 2G for the life of your project? Sorry about the D1, I should look closer. I spent several weeks trying to get a ESP-01S to talk to a HotSpot using AT commands. Where are you going to send your data to?
Re: GSM SIM800L
Hi, I thing that 2G is neccessary just for internet (wifi) and my SIM800L will used as a SMS. Do you think that SMS is not in corellation with 2G?
Re: GSM SIM800L
https://en.wikipedia.org/wiki/2G says that 2G supports SMS.
ESP32 SIM800L Publish Data to Cloud wit ... Tutorials might be helpful. I bought one of these only to find out that GSM did not mean it would support 3G.
Good luck.

Hi Jadro,
I've got also this, how did you get it to work? Do you have any scripts for this? If I could ask you for your help, because I'm new to microcontrollers, and this is my first project. I've got the V 1.3 the similpier one.
Thanks,
Janos
