Passkey corruption when using pc-ble-driver-py

Stephan Walter

We are using the latest master of pc-ble-driver-py. Pairing using a passkey fails frequently. The problem seems to be that the frame with the passkey contains a corrupted value.

Since ble_driver.py or ble_adapter.py do not offer methods for passkey entry, we are using the sd_ble_gap_auth_key_reply method of the underlying driver.

Example: After getting a on_gap_evt_auth_key_request, we call sd_ble_gap_auth_key_reply with passkey=913858

pk = util.list_to_uint8_array(b'913858').cast()
driver.sd_ble_gap_auth_key_reply(self.adapter.driver.rpc_adapter, self.conn_handle, driver.BLE_GAP_AUTH_KEY_TYPE_PASSKEY, pk)

The pairing fails with BLE_GAP_SEC_STATUS_CONFIRM_VALUE. Looking in the debug output, the following packet was sent:

pc_ble_driver_py.ble_adapter DEBUG       24 ->  [00 80 00 00 01 01 39 31 33 38 c8 69 ] type:     VENDOR_SPECIFIC reliable:yes seq#:6 ack#:1 payload_length:c data_integrity:1 header_checksum:64 err_code:0x0

Note the bytes 39 31 33 38 c8 69. The expected values would be 39 31 33 38 35 38.

Here are some more examples:

passkey: 308558 packet: [00 80 00 00 01 01 33 30 38 35 58 a9 ]

passkey: 045296 packet: [00 80 00 00 01 01 30 34 35 32 c8 69 ]

passkey: 773757 packet: [00 80 00 00 01 01 37 37 33 37 c8 69 ]

When the correct passkey is in the packet, pairing works (BLE_GAP_SEC_STATUS_SUCCESS).

Is there anything we are doing wrong?

Below is some more context from the debug output:

    Hi.

    Could you provide me with the test you did so I can share it with the development team?

    I can make the ticket private if you don't wish to share that with anyone else beside Nordic.

    Best regards,

    Andreas

    Hi Andreas,

    I have written a short script with which you can reproduce the problem, both on nRF51 or nRF52 dongles.

    The script connects to a peripheral (address is hard-coded) which should support security.

    To simplify it, I always send a fixed passkey of 123456, which of course causes bonding to fail, but the invalid bytes can be seen in the log, starting with [00 80 00 00 01 01 ...

    The problem occurs roughly 1 out of 10 attempts, so you will have to run it several times and inspect the log.

    Hi Andreas,

    I have only been able to reproduce it in the "Release" build.

    In pc-ble-driver v4.1.1, I added some logging in file src/sd_api_v5/ble_gap_impl.cpp:

    uint32_t sd_ble_gap_auth_key_reply(adapter_t *adapter, uint16_t conn_handle,
    uint8_t               key_type,
    uint8_t const * const key)
{
    const encode_function_t encode_function = [&](uint8_t *buffer, uint32_t *length) -> uint32_t {
        printf("encode key:%02X %02X %02X %02X %02X %02X\n", 
               key[0],key[1],key[2],key[3],key[4],key[5]);
        return ble_gap_auth_key_reply_req_enc(
            conn_handle,
            key_type,
            key,
            buffer,
            length);
    };

    const decode_function_t decode_function = [&](uint8_t *buffer, const uint32_t length, uint32_t *result) -> uint32_t {
        return ble_gap_auth_key_reply_rsp_dec(
            buffer,
            length,
            result);
    };

    printf("sd_ble_gap_auth_key_reply key:%02X %02X %02X %02X %02X %02X\n", 
               key[0],key[1],key[2],key[3],key[4],key[5]);

    return gap_encode_decode(adapter, encode_function, decode_function);
}

    Here's the output from a failure:

    passkey request
sd_ble_gap_auth_key_reply key:31 32 33 34 35 36
encode key:31 32 33 34 10 40
      19 ->  [N/A] type:                 ACK reliable: no seq#:0 ack#:7 payload_length:0 data_integrity:0 err_code:0x0
      20 ->  [00 80 00 00 01 01 31 32 33 34 10 40 ] type:     VENDOR_SPECIFIC reliable:yes seq#:4 ack#:7 payload_length:c data_integrity:1 header_checksum:36 err_code:0x0

    It seems that the closure data gets corrupted (are closures even a thing in C++? I'm a complete beginner here, as I only do C).

    Hi.

    Thanks for the input, may I ask which compiler and platform you're using?

    Best regards,

    Andreas

    Hi again.

    Thanks for the information, I've forwarded it to the development team, they will do some testing.

    I will get back to you when i know more :-)

    Best regards,

    Andreas

    Hi again.

    Hei, kan du be kunden å endre koden i on_gap_evt_auth_key_request fra:
    Can you try to change the following in the code:
     pk = util.list_to_uint8_array(b'123456').cast()
        driver.sd_ble_gap_auth_key_reply(adapter.driver.rpc_adapter, conn_handle, driver.BLE_GAP_AUTH_KEY_TYPE_PASSKEY, pk)
    And change it to this:
     pk = util.list_to_uint8_array(b'123456')
        driver.sd_ble_gap_auth_key_reply(adapter.driver.rpc_adapter, conn_handle, driver.BLE_GAP_AUTH_KEY_TYPE_PASSKEY, pk.cast())
    Best regards,
    Andreas
