Hi, Guys.
I am developing a custom hardware keyboard using the ble_app_hids_keyboard example source code of SDK17.1.0.
The basic keyboard function works well.
And Caps Lock also works well on iPad.
After that, I implemented three additional functions, keyboard + mouse + consumer control, as in the link below.
However, when I connect it to iPad and test it, the basic keyboard function works well, but the Caps Lock function does not work.
That is, I disabled the iPad's Settings - General - Keyboard - Hardware Keyboard - [Switch Languages using Caps Lock].
Then, the Caps Lock function should work, but the custom board I am developing does not work, so only lowercase letters are entered.
It is the same source as the link above, but I do not know how to make Caps Lock work on iPad. Please help me.
In other words, when I add the mouse and consumer control, Caps Lock does not work on iPad. How can I fix this problem?
My source code is:
