Unable to understand pining of mDot

[Capecchi Olivier]

Hello all,
I have a very basic question : I’m not able to understand the pining of the mDot, even after reading and reading and reading the Developper Manual…

What I don’t understand : the LoRA pins (page 27 of the Manual) are refered as PB_xx… What are those PB_xx pins ? I really don’t understand. I have 20 pins on the mDot, why is it not simply explained which one of those 20 pins are the LoRa pins ?

What I want to do : to interface a development board I have with a mDot, the mDot being used only to send a message through LoRa. I would like to use UART or SPI to do so.

Thanks for your help,

Olivier

Olivier,

We have a really nice diagram on the mbed mDot platform page that shows the pin names and different functions available on each pin.

The mDot ships with our factory AT firmware, which will probably suit your needs. You can also find it on our developer page.
