Blynk works well with WiFi, Ethernet, Bluetooth, even USB.
And what about GSM (aka telepathy)?
Yes, yes. We have some good news for you.
Who wants to be the first to try Blynk with cheap SIM800 or SIM900 modules?
Please reply in this thread, and tell your module model.
P.S. SIM800L can be found for $3.80 on AliExpress
