I just got back from the field. Just having tested out my Android Phone dashboard for the FrSky telemetry module.
I am just so excited it worked as planned, i had to tell someone.. (My wife didn't show the "proper" enthusiasm i feel it deserves )
Summary:
- DIY 6 cell LiPo voltage sensor on a T-REX 600
- Add cheap RS232-Bluetooth bridge to the FrSky Tx module
- Make android application that connect to bluetooth, parses the values, and reads them aloud to me in an earpiece.
Application is still fairly simple. (scaling and channels are currently hardcoded etc). But i now feel i have a nice framework to keep developing.
I was concerned that the BT connection might affect either of the streams to/from the helicopter, but i didn't notice any issues at all.
It was a whole lot more convenient than dragging the laptop to the field
Next is:
- configurable channels. (name, texts, scaling, unit, filters etc etc)
- more options for logging, including CSV logging
- Possibility to set FrSky internal alarms
- Alarms in phone
- ..
