Central HIDS example can't connect with BLE HOGP mouse

[tadakado]

Hi, I tested Central HIDS example in nRF Connect SDK 2.1.0 with NRF52840DK. The example works with my BLE keyboard, but does not work with my BLE mice. The followings are messages for the BLE mice. How can I modify the example to connect them? The first mouse can connect with nRF Connect for Desktop, and the other can't. I have attached the connection information.

Hi,

The sniffer traces with data PDU are attached. Sorry for incomplete data in the previous post.

Also, below is the logs for different BT_MAX_PAIRED settings.

Hi,

The sniffer can both get packets in a connection and decrypt encrypted packets (see nRF Sniffer documentation for details). That is needed for it to tell us anything useful, but it may not be relevant in this case.

I suggest focusing on that bt_conn_set_security() returns -ENOMEM. Did you try to increase CONFIG_BT_MAX_PAIRED? Or can you try to dig deeper with a debugger to pinpoint  more closely where the error originates?

Hi,

This might be more detailed information for ELECOM mouse errors.

(1) Sniffer trace (decrypted) (2) Call stack (3) Debug log

I guess I need to set a larger buffer size somewhere as the last part of the log below says 

(BT_MAX_PAIRED, BT_GATT_DM_MAX_ATTRS, BT_HOGP_REPORTS_MAX are not the answer to resolve the problem)

I am not able to pinpoint the exact issue from here. Have you attempted to debug to see exactly where the error comes from? Which API call returns -ENOMEM, and how far down can you track it? That should give a good indication on what needs to be adjusted.

[tadakado]

I found that the error comes from L417 "discovery_process_characteristic" in gatt_dm.c https://github.com/nrfconnect/sdk-nrf/blob/v2.1.0/subsys/bluetooth/gatt_dm.c#L417

However, this is not the reason why the Central HIDS example does not work with ELECOM mouse. Below is a list of attributes stored during the connection. In Logitech, all handles are stored sequentially, while ELECOM lacks some handles. This is a variation of behavior among BLE peripherals.

===> It fails as handle 0x0018 does not exist.

Why, this happens? I capture BLE packets (1) ELECOM + Central HIDS example (2) ELECOM + iPad. The example reads GATT database by "Find Information 0x04", while iPad does by "Read by Type 0x08". (See details in the attached files. You need filter ATT packets by "btatt".) I also found that Windows 10 also use "Read by Type". This causes the lack of information in the Central HIDS example.

So, I wan to change the method to read GATT database by not "Find Information" but "Read by Type" like iPad does. How can I do this?
