why it return SUCCESS in SD7.0 while fail in SD6.0?

[jimlin]

Hi all,

I found something different between SD6.0 and SD7.0:

1.KB bonds with iPad successfully;

2.Click OFF the bluetooth button in iPad setting, then KB goes into advertising mode;

3.Click any button in KB continuously and click ON the bluetooth button in iPad setting;

4.Sometimes, the iPad indicates CONNECTED and the KB works well, but, sometimes KB does not work;

5.For SD7.0 and SDK6.0, the err_code returns SUCCESS when keys_send() called, no matter the KB works well or not;

6.For SD6.0 and SDK5.2, the err_code returns SUCCESS when KB works well, but NOT SUCCESS when KB does not work with iPad indicates NOT CONNECTED;

So, for SD7.0 and SDK6.0, there will be one condiction sometimes: the iPad indicates KB connected but not response any KB function, and the firmware could not detect it by err_code returned from SD.

But, it never happen in SD6.0 and SDK 5.2, with the same operation.

Could you help to confirm this ?

Thanks for reply.

What example are you working on? ble_app_hids_keyboard? Have you modified it? How often is sometimes? What error code is returned? Please edit your question to include the information.

Yes, ble_app_hids_keyboard in SDK 6.0. The frequency is about 5%. When the iPad did not response, the err_code returns SUCCESS, not NOT SUCCESS.

I don't really understand. What is the difference? You say SD7.0 and SDK6.0 returns SUCCESS no matter if keyboard works or not, and that SD6.0 and SDK5.2 returns SUCCESS when it works, but not NOT SUCCESS when it doesn't work?

Please clarify.
