GrabbaFirmwareAPI Class Reference

Description

Provides access to firmware-related functionality of connected Grabba devices.

This API provides the ability to query Grabba device firmware; additional functions relating to firmware upgrading will be added in a future release.

Note

This is a static class; object construction is unnecessary and consequently disabled. Subclassing is strongly discouraged.

Method Documentation

init()

- (instancetype _Nullable) init

Not callable (NS_UNAVAILABLE) since this is a static class.

version()

+ (NSString* _Nonnull) version

Query the firmware version number of a connected Grabba device.

This is a non-blocking call; the driver caches the firmware version number internally.

Firmware version number string (e.g. "G1-O v2.1.200") of the connected device if there is one, otherwise an empty string.
