This one.
In the capture, the HID commands are classified as Bluetooth Attribute Protocol (ATT) packets and each keystroke is a pair of key down and key up actions with corresponding packets.
If I send a space keystroke from my app, Wireshark reports first a packet with an ATT value of
00002c0000000000for key down, then another packet with a value of0000000000000000for key up. The second packet is sent ~15 milliseconds after the first one.When the issue is happening this sequence is jumbled up because some packets are missing. In addition, for the few successful keystrokes, the delay after which the key up action is sent is much higher (~150 ms).
@Gordon, have you managed to reproduce the problem with your Linux PC?
