Cellular Receiver

[aaron4522]

Research cellular receivers that we could buy for Pi. This would allow us to SSH to the boat while it is on the water and lets us reboot the boat or send shell commands to the boat. This would also let us get cm level precision with the maCORS towers (https://github.com/PittSailbot/Sailbot/issues/3).

Requirements:

• Removable SIM card (so we can use one from a phone and don't need to set it up with a plan)

Receiver added to order.

Use either Remote.it, RemoteIot?, SocketXP, or VPN to home for LAN access. Research which method would be best.

LoRa is also technically possible to set up serial communication but more scuffed. According to another team 900mhz still cut out. https://www.instructables.com/LoRa-Messenger-for-Two-Devices-for-Distances-Up-to/
