There has been some projects around turning Mavlink via 433/900Mhz radios into Bluetooth to allow easy multiple use from laptops and tablets. There is also experimental code to allow the 3DR radios to use multiple receivers to allow a radio on tablet & ground station.
My idea is as follows:
- Two radio inputs - Auto switch between, e.g. 3DR 433 & RFD900 - allow me to switch models and make no changes to my setup, automatically selecting which has link.
- Serial / USB connection - I don't want bluetooth or the overheads with bluetooth for my ground station, direct connection pass through to the current radio is important.
- Bluetooth - love the idea of local bluetooth for tablets
- Simple display - built in display using a simple OLED output, just nice to look at the source both for the configuration of the device, which radio is used etc, but also basic mavlink information.
The last entry there is probably the most unusual part. ANT+ is a protocol which is used by sensors such as heart rate and speed/cadence on bikes. It is common on watches for example. I would love to have ANT+ output to allow me to use some interesting devices coming up. For example you can buy heads up displays for sunglasses with ANT+ - yes we can do our own heads up display, nicer, but I like the off the shelf options.
What else would you do/add? Would you try and transmit to one of the other telemetry protocols.
