BLEPeripheral.addService(UUID:string, primary:boolean)
BLEPeripheral.addService('XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX', true) //for primary service
BLEPeripheral.addService('XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX', false) //for non primary service
BLEPeripheral.addCharacteristicToService(ServiceUUID:string, UUID:string, permissions:number, properties:number)
https://developer.android.com/reference/android/bluetooth/BluetoothGattCharacteristic.html the link above is for permissions and properties constants info
Permissions:
Properties:
BLEPeripheral.addCharacteristicToService('XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX', 'XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX', 16 | 1, 8) //this is a Characteristic with read and write permissions and notify property
BLEPeripheral.sendNotificationToDevices(ServiceUUID:string, CharacteristicUUID:string, data:byte[])
BLEPeripheral.sendNotificationToDevices('XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX', 'XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX', [0x10,0x01,0xA1,0x80]) //sends a notification to all connected devices that, using the char uuid given
note:use this only after adding services and characteristics
BLEPeripheral.start()
.then(res => {
console.log(res)
}).catch(error => {
console.log(error)
})
In case of error, these are the error codes:
BLEPeripheral.stop()
BLEPeripheral.setName(name:string)
This method sets the name of the device broadcast, before calling start
.
BLEPeripheral.setName('RNBLETEST')
DOCs and project is under development Any help would be welcome... feel free to contact me
