I have entered this competition with your board.
Sorry if they have restrictions.
Not me I would invite all.
I will use the SoDaQ ExpLoRer kit.
Using LoRa, BLE & 508a for build a BLE advert system for the A96 road here in Scotland.
This project will use peer to peer LoRa modems.
We will use the 508a with public-key.
BLE will be used to deliver URL adverts.
Adverts can be updated to the road from the office.
I have removed the LoRaWAN protocol due to security issues.
I will build my own protocol for the use case.
This system will be off grid WAN with full hardware security.
After all, we are going to build
The Best in Class solutions for our IoT future.
Lets, protect everyone, all the time, show the IT world how we swing!
I hope all that can enter.
Best regards from SCOTLAND
