connect clj/s macro

(connect device-address)

(connect device-address properties)

Establishes a connection between the application and the device with the given address. A device may be already connected and its GATT services available without calling connect, however, an app that wants to access GATT services of a device should call this function to make sure that a connection to the device is maintained. If the device is not connected, all GATT services of the device will be discovered after a successful call to connect.

|device-address| - The Bluetooth address of the remote device to which a GATT connection should be opened. |properties| - Connection properties (optional).

This function returns a core.async channel of type promise-chan which eventually receives a result value. Signature of the result value put on the channel is [].

In case of an error the channel closes without receiving any value and relevant error object can be obtained via chromex.error/get-last-error.
