NRF51822 (HID keyboard example) and android kitkat

[Aashish Patel]

Hello,

I am trying to verify hid_keyboard_demo app running on nRF51822 with android running device.

I have tested it with my phone running android kitkat and windows 8 system it works fine.

But with my custom board running android 4.4.2 (asop) am not able to input characters.

I am able to pair and connect.

Nordik_keyboard does not appear as Input device in android Settings -> Language & input

Has anyone tested it with android (asop) device ?

Does system(android) need to support specific input driver for this keyboard to work ?

I've tested this on a Nexus5 when it had 4.4.2 and I also ran a test just now with Android 4.4.4 on a Nexus 5 as well as with a Galaxy S5 with 4.4.2. They all connect and can use the HID keyboard example as input, but there's an option in the Bluetooth setting as well whether or not to use this as input source. Have you check this?

Have you modified your Android version in any kind? The HID keyboard requires a bonded connection.

If you're still having issue, I would check the on air communication with a sniffer.

Thanks for your reply. But I have already tested it on android phone but my ques was regarding custom board running android kitkat 4.4.2 (ASOP).
