complete beginner on arduino here and i'm very confused with this...
i have a sim800l module v2 with an antenna connected to an Arduino Uno and whenever i plug the usb port into my computer, the led on the "d6 net" blinks normally when there's no connection but the "d2 ring" part doesn't light up
in most videos that d2 ring part always lights up after plugging it in, and idk what is causing it not to light up.
any help would be appreciated...
thanks!
Will you post a link to the video you followed?
Is your SIM800L power pin marked VCC (V1 SIM800L) or 5VIN (V2 SIM800L)?
its v2 (5vin)
@cryingnewbie - Can you use an external 5vdc power supply? It is possible that when you send data the power needed by the SIM800L to make the call/sms rises above the level your Arduino can source. By the way; D6 LED is the ring indicator (a call incoming or outgoing - @7:23, see the red LED lit to the right of the slow blink LED D6).
