Functions

suspend fun close()

Closes the connection

fun observe(characteristic: String, interval: Long = 5000, owner: LifecycleOwner? = null, callback: OnCharacteristicValueChangeCallback<ByteArray>)

Observe a given characteristic

fun observeString(characteristic: String, interval: Long = 5000, owner: LifecycleOwner? = null, charset: Charset = Charsets.UTF_8, callback: OnCharacteristicValueChangeCallback<String>)

Observe a given characteristic

suspend fun read(characteristic: String): ByteArray?

suspend fun read(characteristic: String, charset: Charset = Charsets.UTF_8): String?

Performs a read operation on a specific characteristic

fun readAsync(characteristic: String, callback: (ByteArray?) -> Unit)

fun readAsync(characteristic: String, charset: Charset, callback: (String?) -> Unit)

Performs a read operation on a specific characteristic

fun readRSSI(): Boolean

Requests a read of the RSSI value, which is updated on the rsii variable

fun requestMTU(bytes: Int): Boolean

Request a MTU change Note: even if this method returns true, it is possible that the other device does not accept it, so Android will fallback to the previous negotiated MTU value. This will be reflected by the mtu variable.

fun stopObserving(characteristic: String)

Stops observing the characteristic

fun write(characteristic: String, message: ByteArray): Boolean

fun write(characteristic: String, message: String, charset: Charset = Charsets.UTF_8): Boolean

Performs a write operation on a specific characteristic
