HOGP / ble_app_hids_keyboard / iOS 7.1 / softdevice versions

[davman]

Hi,

Been testing the ble_app_hids_keyboard that comes with the nrf SDK and have some questions.

Notes:

• The PCA10001 EK is V2.2.0 (2014.04)
• I downloaded the nrf SDK today (filename: nrf51_sdk_v5_2_0_39364), so I assume it's the latest source files. Please confirm.
• as the example is for the nrf6310-board, gpio mods were made in the h-file.

Questions:

• Which S110 softdevice is supposed to be used? When I use the S110 5.2.1 softdevice, the device doesn't seem to work/advertise at all (confirmed to be same on the HRS example made for the PCA10001 board). When I switch to S110 6.0.0 HRS works, so does the ble_app_hids_keyboard example.

• Tested in Master-Control panel and can see data coming through. Paired with Mac OS X 10.9.2, every click on Button0 sends one character to the mac, H... E... L... etc. Paired with iOS 7.1, clicking btn0 does nothing (notes is in foreground). Any known issues here? (have tried unpair/re-pair, reboot phone etc etc no succes, went back to mac, works. Confirm using another BLE HID devices and that sends data to iOS.)

• Should this code be considered production stable for HID over GATT?

• Are there other HID keyboard examples that I should test as well?

Also tested with BlueZ under Ubuntu, here the result is a bit different, it connects successfully but pairing fails (using bluetoothctl pair), but the hid is still created in /dev/input/event4 !?

Anyone?

I too would appreciate a response to this. I am having the same problem with iOS 7.1

Hi davman and Jackson,

The problem you see with HID Keyboard not working with iOS is the same as what is described here -> devzone.nordicsemi.com/.../hid_mouse-search-ok-on-iphone-5s-but-connect-failed,anybody-meet-this-before

The changes done to the HID Keyboard example in SDK 5.2.0 make it incompatible with IOS. As the text in the above link says, it has been reported internally and will be fixed in the upcoming SDK releases.

@Which S110 softdevice is supposed to be used?

Please use S110 SoftDevice v6.0.0 when working with SDK 5.2.0. - This is mentioned in the release notes of the SDK (See Supported SoftDevices section).

@- Should this code be considered production stable for HID over GATT?

SDK code should not be considered production ready.

Cheers, Balaji
