HID Keyboard Example Crashes Windows Bluetooth Driver

Postby gnorkus » Tue Mar 27, 2018 1:42 pm

Hi All,

I'm a new developer here. Windows doesn't seem to like the HID Keyboard example from asterics (https://github.com/asterics/esp32_mouse_keyboard). The device connects fine, but after a short while, however, my Bluetooth driver on the Windows device hangs and all the Bluetooth devices, including keyboard and mouse, stop functioning. Only a reboot will help. I've cobbled together a somewhat working HID Keyboard example using as a basis for my own, to perhaps avoid the problem, but to no avail.

My own HID example is similar to asterics, but provides no mouse output. The idea is to use BLE only (not dual mode), and allow a user to send 3 different keystrokes to an attached computer. I modified the above mentioned code by removing most of the mouse/keyboard events and replacing it with a task called button_reader. I changed the appearance to BTM_BLE_APPEARANCE_HID_KEYBOARD, set the device mode to ESP_BT_MODE_BLE, set the debug logging to verbose in make menuconfig (I don't have a jtag debugger, until tomorrow) and the iocap to ESP_IO_CAP_NONE so that I don't need a PIN.

I'm running a Sparkfun ESP32 Thing with the "make menuconfig" set to autodetect the xtal frequency, and debug log messages sending out to COM8. Below is the code I used to replace the ble_hidd_demo_main.c file from asterics. It builds and flashes fine. I'm using the esp-idf from yesterday (from GitHub).

Since none of my other devices are causing such a problem, it's a sure bet that the ESP32 code is causing the problem. Can anyone give me a hand with this? I've been banging my head for a month on this, and I'll probably get fired for it. On a side note, the ESP32 seems to be drawing a lot more power than I would expect for BLE. The example used in Arduino for BLE to turn on an LED from an Android phone draws only 150 or so mA, whereas the heat coming from the ESP32 seems to suggest a lot higher draw (I still have to check).

After the code is a dump of my log over the COM8 port. My windows system log doesn't seem to note anything, so the Windows driver (chegewara had a nice adjective to describe it) seems to be choking, perhaps overflowing some buffer??? To repeat this failure, you may need to invoke the sending of the keystroke about 100 times. The hid_dev_send_report messages in the log reflect my button presses being sent as keystrokes (two for everypress).

Much Thanks In Advance To Any Who Reply!

Re: HID Keyboard Example Crashes Windows Bluetooth Driver

Postby gnorkus » Thu Mar 29, 2018 11:06 am

To any who might be able to help but want to know my setup, please do the following:
1. Go to your esp-idf workspace
2. git clone https://github.com/asterics/esp32_mouse_keyboard
3. Replace the ble_hidd_demo_main.c with the code I have in my first post.
4. make menuconfig (use your own setup, crystal, COM port, etc...)
5. make flash
6. On Windows 10, go to the Bluetooth device in settings and connect the device
7. Keep pressing the button attached to GPIO_0 until the system no longer accepts button presses

Thanks!

To the board moderator: Is it possible to send a message to the user chegewara, kindly requesting assistance, or is that considered poor etiquette?

I will try to help (studying code now), but here is the first issue:

Code: Select all

xTaskCreate(&button_reader, "buttonread", 2048, NULL, tskIDLE_PRIORITY, NULL);
https://github.com/espressif/esp-idf/is ... -375378695

And try with higher stack, maybe 8-10kB.

Very interesting - how does ESP32 report itself as HID/USB device to PC OS?

With special set of characteristics. There is also characteristic which value is report map with all informations about HID device and how values will be packed in structure and send when hid peripheral has something to report.

In this case, it reports itself as keyboard with the name
"EnvisicPedal"

In ble_hidd_demo_main.c, that name is assigned to hid_device_name_fabi at line 59, and sent to the Windows OS via the hidd_event_callback at line 100 using the esp_ble_gap_set_device_name function.

Hi Chegewara and Deouss,

First off.. THANKS!

Second, the replies I am sending are delayed because the moderator needs me to be a part of the forum just a little more time before the replies are immediately posted.

I modified the code to the following:
xTaskCreate(&button_reader, "buttonread", 8192, NULL, tskIDLE_PRIORITY+1, NULL);

And now it works! Amazing, but it also seems to find it's way to reconnecting if I disconnect the device. I am going to modify the code so that the device can go into deep sleep, be woken up by a button press, and then check if it can reconnect.

Chegewara, I'm guessing that the idle priority was killing the ability to send properly timed responses back to the Windows driver. I'm also guessing that the stack size was more likely the culprit, due to the fact that the original code had '5' instead of idle priority.

Should I assume that the reconnect should now occur without troubles, or do I need to add anything extra to the nvs lines?

Thanks again!

Hi Chegewara,

Well. That's not the issue, evidently. But it slows down the onset of the problems.

If I leave the device connected for a few minutes, the windows settings starts toggling the Envisic Pedal from Connected to Paired at a rate of about 1 time every 2 to 3 seconds. Hmmm.... After that starts happening, I cannot reconnect the device until I do a restart.

Something else must be going on...

Can you describe that process?
Booting must be changed or flashed?
Maybe you could direct me with some materials
Thanks
