SIM800c - Cannot init Modem

Need Help With My Project
1

Hi all, first of all… WE LOVE BLYNK!

In our new project all module work perfectly, but our SIM800C (in particoular with this shield) is not initializing the modem.

We have inverted TX and RX used on PIN2 e PIN3 having:
TX - PIN2
RX - PIN3

After this we have the bound rate of 115200 … ok

But now using blynk 0.4.7 on Arduino Nano we have no modem init…

Any Idea? We need help… :cry:
