nintendo pro gamepad can't works well when connected with BT

[wurcyc]

When connect nintendo pro gamepad through BT, in below function
the size is always 12, and the data[0] is always 63(JC_INPUT_BUTTON_EVENT 0x3F)
static int joycon_ctlr_handle_event(struct joycon_ctlr *ctlr, u8 *data,
int size)
{
int ret = 0;
bool match = false;
struct joycon_input_report *report;
int i;
hid_info(ctlr->hdev, "[wurc]joycon_ctlr_handle_event:size[%d] data[0] %d\n", size, data[0]);
for(i =0; i < size; i++)
{
hid_info(ctlr->hdev, "[wurc]data[%d]=[%x] \n", i, data[i]);
}
//hid_info(ctlr->hdev, "wurc - joycon_ctlr_handle_event---1\n");
if (unlikely(mutex_is_locked(&ctlr->output_mutex)) &&
ctlr->msg_type != JOYCON_MSG_TYPE_NONE) {
switch (ctlr->msg_type) {
case JOYCON_MSG_TYPE_USB:
if (size < 2)
break;
if (data[0] == JC_INPUT_USB_RESPONSE &&
data[1] == ctlr->usb_ack_match)
match = true;
break;
case JOYCON_MSG_TYPE_SUBCMD:
hid_info(ctlr->hdev, "[wurc]JOYCON_MSG_TYPE_SUBCMD-1:size[%d] data[0] %d\n", size, data[0]);
if (size < sizeof(struct joycon_input_report) ||
data[0] != JC_INPUT_SUBCMD_REPLY)
break;
hid_info(ctlr->hdev, "[wurc]JOYCON_MSG_TYPE_SUBCMD-2\n");
report = (struct joycon_input_report )data;
hid_info(ctlr->hdev, "[wurc]JOYCON_MSG_TYPE_SUBCMD-3: replyCmd[%d]-sendCmd[%d]\n", report->subcmd_reply.id, ctlr->subcmd_ack_match);
if (report->subcmd_reply.id == ctlr->subcmd_ack_match)
match = true;
break;
default:
break;
}
if (match) {
hid_info(ctlr->hdev, "[wurc]joycon_ctlr_handle_event ---2\n");
memcpy(ctlr->input_buf, data,
min(size, (int)JC_MAX_RESP_SIZE));
ctlr->msg_type = JOYCON_MSG_TYPE_NONE;
ctlr->received_resp = true;
wake_up(&ctlr->wait);
hid_info(ctlr->hdev, "[wurc]joycon_ctlr_handle_event ---3\n");
/ This message has been handled */
return 1;
}
}
And we have checked the data, it is like below
3f 00 00 08 70 85 5f 8c 70 7c 3f 8a
3f 00 00 08 60 85 5f 8c 70 7c 2f 8a
3f 00 00 08 70 85 4f 8c 60 7c 5f 8a
3f 00 00 08 70 85 6f 8c 70 7c 3f 8a
3f 00 00 08 70 85 6f 8c 60 7c 4f 8a
3f 00 00 08 70 85 7f 8c 60 7c 3f 8a
3f 00 00 08 70 85 7f 8c 70 7c 3f 8a
3f 00 00 08 70 85 6f 8c 70 7c 4f 8a
...

While connected through USB, nintendo gamepad can works well and its data is like below
the data size is always 64

Do you know what cause gamepad send wrong data? it seems that the size should be 64 and the data content is also wrong in BT connection.
