Disconnected: 0 BLEHci.remote_user_terminated_connection [using pc_ble_driver_py]

[voldemort]

Hello,

I am using the nordic nRF52840-DK and trying to connect to a nRF52840-Dongle and sending/receiving data to custom services and characteristics using pc_ble_driver_py. I modified the heart rate collector.

But the problem is that when I am connected to the Dongle the connection last 25 to 30 secondes and I receive a message : "Disconnected: 0 BLEHci.remote_user_terminated_connection" and the error message is : "line 477, in write_req attr_handle = self.db_conns[conn_handle].get_char_value_handle(uuid) KeyError: 0". However, when I use the nRF connect mobile/PC version I don't have this problem so I think it is a problem with my code. I check it out if there is some time out equal to like 25_30 secondes but I didn't find any solution.

Could someone help me please to find some solution.

Thanks in advance.

Cordially

Disconnected: 0 BLEHci.remote_user_terminated_connectio

This means that  sd_ble_gap_disconnect() was called on the peer, with the reason BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION. If you can debug your peer you should be able to find where this is called.

Hello,

I edited the function connect() and I added a tag = 1 = CFG_TAG (the macro in the line number 33), I don't have anymore the problem BLEHci.remote_user_terminated_connection neither the errors.

However, after like 250~253 secondes the connection will stop and I receive the message below :

---> Disconnected: 0 BLEHci.conn_interval_unacceptable

Does anyone have any solution?

Thanks in advance.

Great, can you share the sniffer file (.pcapng) here?

I have issues exporting data with wire shark, I have found a way to get them on a txt file. you will find it in the attachments.

Wireshark crash everytime I want to save the log. However, I found a way to get the log in a text file and if you prefer I could save them in a CSV file. In the text file which I shared, you find the " Control Opcode: LL_TERMINATE_IND" at the line number 140758.

Please try to make the pcapng file work. Maybe check that you stop sniffing before saving, try a restart of PC and wireshark etc.

Hello Kenneth,

I tried to solve the crash problem by installing wireshark on different PCs and I followed step by step as it mentionned in this link https://infocenter.nordicsemi.com/pdf/nRF_Sniffer_BLE_UG_v3.2.pdfhttps://infocenter.nordicsemi.com/pdf/nRF_Sniffer_BLE_UG_v3.2.pdf .

But everytime I want to save log,  wireshark crash, I  have seen that this is a bug 14631 with Qt and there is no update since 4 years to this: https://devzone.nordicsemi.com/f/nordic-q-a/15429/nrf-sniffer-crash-can-be-fixedhttps://devzone.nordicsemi.com/f/nordic-q-a/15429/nrf-sniffer-crash-can-be-fixed .

when I try to click on file save, the buttons are not enabled and when I click on the red stop icon wireshark crash and exit the app.

Could you perhaps try to use my python code and sniff if your sniffer works well.
