Bluetooth Adapter for Keyboard/Mouse FAQ

What USB devices does the Adapter work with?

The adapter works with only USB keyboards and mice. It does not work with any other types of USB devices such as game controllers, video capturing boards, audio devices or serial port adapters.

Does the adapter have lag?

For USB to USB bridging, there is no noticeable lag.

For Bluetooth connection, as a wireless device using shared transmission channels, it is not as quick as wired connection but it is acceptable for normal typing use. Your mileage may vary for gaming applications though. There is no difference between a keyboard connected to the Adapter and any wireless keyboard with regarding to latency.

May I use the Adapter with a USB hub?

If the USB keyboard/mouse you intend to use does not contain a built-in hub, then yes you can use a hub but there can be only two device connected to the hub. This can be useful if the device consumes large amount of current (in that case an externally powered hub is used). In some very rare cases, the device is not compatible with the adapter but is through the hub (i.e., the device does not work with the Adapter directly, but it works with the hub, and the hub works with the adapter).

If the USB keyboard already contains a build-in hub, you can connect one more device to that hub. In that case no more hub can be added.

Can I use a power bank to power the adapter?

Absolutely. Virtually any power bank will do. So you can bring the adapter on the road.

How much current can the adapter supply?

The adapter simply passes the power from the male connector the the female connector so the limit is up to the power source. The adapter itself consumes about 40mA of current.

When I connect a USB RFID reader, magnetic strip reader or some other keyboard-emulating devices to the adapter, the output is losing characters. What can I do?

This is because those USB devices output data at high rate. It is ok with wire USB connection but Bluetooth wireless may not able to handle that rate. We anticipate this situation and have a throttle feature in the adapter to slow down the data. To enable this feature, enter command mode and type in the following:

> set time throttle 10
> save
> reboot
 

This will add 10ms delay between each character. You should see the output slowing down. If that is not enough (still missing characters), increase the delay to 20, 30, …, until all characters are output reliably. Setting delay to zero instructs the adapter to send out characters as soon as it receives them, effectively disables the feature.
