Send a message from a Bluetooth chip to a satellite

Goal: a message from a CC2755P10 received by a satellite about 550 km up. Not achieved.

Hardan afternoon to build, flash and register

No recorded steps

Some pieces of it have run. There are no recorded steps for this project, so this page does not give any.

What exists:

  • LP-EM-CC2755P10: Hubble's satellite sample builds, flashes and transmits every 10 s with a 256-bit key; the matching Bluetooth beacon image was heard and decoded on a Mac, 4 of 4 packets in 40 s at -54 to -57 dBm. The board went outside for one pass on 2026-10-18; nothing has reached the dashboard.

What to build next

Send a sensor reading to a phone over BluetoothA reading your phone or Mac picks up over Bluetooth, no pairing
Make a Bluetooth game controller from a LaunchPadPress the LaunchPad's two buttons and a Mac sees a game controller
Asset tracking over BluetoothRun events, trips, run time and load mix for every machine, on your phone, no internet

Every build. The code for all of them is in the GitHub repository.

Evidence and limitsBuilt, flashed and running on the CC2755P10; the Bluetooth beacon decodes on a Mac. No satellite packet has arrived in the dashboard. Ran on 1 board. Results, sources, timing and limits.
