// Configuration Tips
//
// config.json contains various Bluetooth related properties some of which are explained here:
//
// "dfu_service": 1, // 1 will cause the DFU service to be instantiated
// "event_service": 1, // 1 causes the event service to be instantiated
// "device_info_service": 1
// "enabled": 1, // 1 means the Bluetooth stack will be included as standard. 0 means it will not.
// "pairing_mode": 1, // 1 means it's possible to go into pairing mode which will include bringing up the Bluetooth stack whilst in that mode.
// "open": 0, // 1 means there's no Bluetooth security i.e. no need to pair the micro:bit with other devices that want to communicate with it.
// "tx_power": 7, // Transmission power of the Bluetooth radio. A value of 0 - 7 with 0 the lowest power and 7 the highest power.
// "gatt_table_size": "0x700" // Amount of memory (in hex bytes) set aside for the Bluetooth GATT table
// "nested_heap_proportion": 0.75, // Reducing this can sometimes help make enough memory available for all the Bluetooth services you want. Only experiment with this as a last resort.
// MicrobitConfig.h in yotta_modules\microbit-dal\inc\core contains MICROBIT_BLE_SECURITY_LEVEL which can be set to SECURITY_MODE_ENCRYPTION_WITH_MITM for passkey authentication when
// pairing or SECURITY_MODE_ENCRYPTION_NO_MITM to use Just Works pairing.
// A cunning code to indicate during start-up the particular Bluetooth configuration in the build
//
// SERVICE CODES
// A: Accelerometer Service
// B: Button Service
// D: Device Information Service
// E: Event Service
// F: DFU Service
// I: IO Pin Service
// L: LED Service
// M: Magnetometer Service
// T: Temperature Service
// U: UART Service
//
// PAIRING CONFIG
// Note that switching pairing on or off is achieved by setting "open" in config.json to 1 or 0 respectively
// P: PASSKEY
// J: Just Works
// N: No Pairing Required
//
// TX Power Level
// 0-7 taken from tx_power in config.json
// Services/Pairing Config/Power Level
