When --device is omitted or set to 0, the bridge listens to all
broadcasting ANT+ trainers instead of filtering by a specific device.
The actual transmitting device ID is shown in data logs, allowing
users to discover and then filter specific trainers.
Also fix vendorID/productID not being assigned to config struct
which caused ListenForTrainer to receive 0 for both values.
- Add BLE spec constants for service/characteristic UUIDs and signal flag
- Add ANT+ spec constants for data page mask and cycling power page
- Add descriptive comments explaining each constant's origin and purpose
- Add mutex to prevent interleaved log output from concurrent goroutines
- Make logMsg delegate to logPrintf for consistent synchronization
- Buffer events channel to size 1 with select/drop when full
- Close events channel on ListenForTrainer exit so process terminates
- Move flag registration from init() to main()
- Make rootCmd a local variable in main() instead of a package variable
- Log errors from hciconfig down/up reset commands
- Log errors from BLE power characteristic writes
Add comprehensive README.md covering project purpose, CLI usage,
and troubleshooting. Document the udev rule needed to prevent
usbserial from claiming the ANT+ dongle.
Add Tested hardware section listing the ANT USBStick2 and update
setup.md dmesg output accordingly.
Note: the bridge must be run as root to access the USB dongle.
Introduce structured CLI argument parsing using Cobra with three
configurable flags:
--vendor: USB vendor ID (default: 0x0fcf)
--product: USB product ID (default: 0x1008)
--device: ANT+ device number (default: 3001)
Add timestamped logging for all log statements with format
YYYY-MM-DD HH:MM:SS. Log vendor, product, and device values at
startup in both hex and decimal.
Remove hardcoded USB identifiers from main.go and consolidate all
startup logic into cli.go with a dedicated Config struct.
Update ant.go ListenForTrainer signature to accept uint16 for
vendor and product IDs.
