HID Keyboard Demo - works for iOS 7 but not iOS 8

[ki15686]

Hello,

I am trying to use the HID Keyboard Demo (ble_HID_keyboard_template from arduino sdk) . I'm using a RedBearLabs Blend Arduino with the nrF8001.

It works great with iOS 7 (iphone 5)

However, I am not able to get it to work with iOS 8.4 (using iphone 4S). It sometimes pairs (requires multiple attempts), and when it does pair I know it is sending the character "A" to the phone. However, the letter "A" never shows up on the phone.

Am I doing something wrong? Is there a work-around for this?

Thank you, Ken

Hi Ken,

Sorry for the late response. We have received report about the issue with the letter missing on the phone when using nRF8001 with Arduino. We have reported it back to Apple and also doing investigation on our side.

About the issue the the phone sometime didn't pair ( as you mentioned). How frequently does that happen ? What happened when it didn't pair ? Could you capture a sniffer trace when pairing fail ?

I am not doing DFU. Re “pressing the reset button while the firmware is uploading” – I’m using a Redbear Labs Blend board. I don’t know why it works, but it seems to behave better when press the reset button while the Arduino IDE is in the middle of uploading a sketch. Perhaps this is something esoteric and specific to this board.
I am very interested in what Apple has to say re the characters missing. Is Apple good at getting back to you with answers? Or should I not get my hopes up?
