This video shows the iPhone programming the PDU firmware over-the-air.
I am very excited to report that I’ve got over the air programming setup on the Motobrain PDU. I will be able to push firmware updates for the PDU to your phone and you will be able to push those updates to the PDU from your phone. This will allow me to update the code inside the PDU which means I can add new features and fix bugs after you have received your device. This is a huge step forward!
