Blynk with Sim800A get stuck

[psoro]

@vuima ,
Check this example and change it according your pins:

Nodemcu + SIM800L + DHT11/22

Hi @KazaDoor, You can find below a working example using the EspD32 + Sim800L + SHT35. Adapt this basic code to your needs as I’m using the EspD32 rather than the Nodemcu… Keep in mind that, in my case, VCC for SIM800L is managed by a MOSFET.
