Good. This is what i like. Your first video about sim800L was greate too! - (long time ago), keep doing this sim800L its right path. :) thank you. You are greate!
I liked your video. Have two suggestions; you can not connect two antenna simultaneously on the same RF port, furthermore be cautious to handle Lipo Battery, specially in your case where there are naked pins on the Lipo connector which can easily short with each other and and cause fire / damage.
Hi, great video, can you make a video where you use the sim800l module with a microcontroller board that uses micropython to execute tasks, such as sending and receiving SMS? Thanks.

Hello there . Thank you very much for your work. I have a request from you. "mySerial.println("ATD+ +9++++++++++;"); updateSeries(); delay (20000); " . Among these command information, if the called number is busy or rejects the call, it must end the call without waiting for 20 seconds. What kind of code should be written for that.
sir very beautifull voice , prounciation and delivery.thanks

Great Job. Thanks very much.
Your presentation was organised, clear and very relevant.
All of your videos are very helpful and informative. Thanks for your effors!
@5:32 1K resistor should be connected to TX pin. Else it will not function as voltage divider. Otherwise good video. Thanks
I agree with you, I have used the 2k2 + 1k0 resistor as a voltage divider too.
