UART communication between Lopy and Arduino
Good afternoon to all,
I already programmed two Lopy's communicating between each other: the first one gets GPS data and sends it using LORAMAC to the second one.
Now i would like to make a serial communication between that second Lopy and a Sodaq Mbili Arduino board that would send to via LTE network.
The thing is I hardly understand the link between UART, USB, I2C etc. Could anyone help me please?
Thanks to anyone and have a good day,
