hello!

Second MCU pins must be connected to infinity box in following way:

Rx_b to pin 2 of box
Tx_b to pin 3 of box
phone grounded part to box pin 8.

Now about work with second MCU:
it has little difference than first one.
When you boot first MCU you see program connection as soon as you press power button.
with second MCU it is not same.
You must press power button and wait arround 30-40seconds (button pressed all the time)
dont be confused when you see that phone powered On- this is normal.
After phone will power on- you still keep button ppressed and then you will get connection

please try this and reply
