Steps to set up
- On your phone, use the nRF Connect app to Scan for devices and lookfor 'reel board'
- Connect to the device. You'll see a single service - select it
- Request to write to the characteristic by pressing on the upward pointingarrow symbol
- Select 'Text' to enter text instead of hex
- Enter your name (or any other arbitrary text). Multiple wordsseparated by spaces are possible. The font used on the reel displayallows three rows of up to 12 characterswide text. You can force line breaks with a comma.
- Press 'Send' - this will trigger pairing since this is a protectedcharacteristic. The passkey for the pairing will be shown on the board'sdisplay. Enter the passkey in your phone.
- Once pairing is complete the board will show the text you sent. Ifyou're not happy with it you can try writing something else.
- When you're happy with the text, disconnect from the board (exit the app orgo back to the device scan page)
- Once disconnected the board switches over to Bluetooth Mesh mode, and youcan't connect to it anymore over GATT.
If you configure multiple boards like this they can communicate witheach other over mesh: by pressing the user button on the board the firstword (name) of the stored text will be sent to all other boards inthe network and cause the other boards to display '<name> says hi!'.
To reset a board to its initial state (disable mesh, erase the storedtext, and make it connectable over GATT):
- Keep the user button pressed when powering on (or press the reset buttonwhen powered)
- Wait until 'Reseting Device' is shown
