h5_decode error, code: 0x802c, H5 error count

Wael

Hi,

I am getting this error message when using the nRF52 dev board but not when using the nRF51 dongle. I receive few packets and then it disconnects with this error message. here is the log from nRFConnect(version 3.6.1) desktop Bluetooth Low Energy application. I am connecting to an nRF52832 target device with an in house developed application that we have been using for years. 

it’s the nRFConnect that’s faulting because I can see the nRFConnect disconnect with the error message and the target device doesn’t disconnect until few seconds later with BLE_HCI_CONNECTION_TIMEOUT. I cant seem to find any information on this error that is helpful. any help is greatly appreciated. 

4857.2021-05-24T15_07_05.686Z-log.txt

and the log from terminal is this:

    UPDATE: If you're on Mac or Linux J-Link MSD has to be disabled to avoid this, but as you didn't state what OS you were using I assumed you were using Windows.

    I've discussed this with some of the nRFConnect devs today, and we have some ideas, but not yet a certain conclusion I'm afraid. h5 is the protocol used to transmit data between the connectivity and BLE-driver. An error here usually means there is packet loss or something wrong with the data to be transmitted.

    Also, the NRF_ERROR_RESOURCES you're seeing from sd_ble_gap_data_length_update indicates that the SoftDevice being used has not been configured to support the data length for the given connection. What is the NRF_SDH_BLE_GAP_EVENT_LENGTH and NRF_SDH_BLE_GAP_DATA_LENGTH set to in your application?

    Best regards,

    Simon

    Hi Simon,

    thank you for staying on top of this issue for us. I am using a windows machine. and the 

    #define NRF_SDH_BLE_GAP_EVENT_LENGTH 12

    #define NRF_SDH_BLE_GAP_DATA_LENGTH 251

    I did try to change the NRF_SDH_BLE_GAP_DATA_LENGTH to 23 and that did not help. I also want to repeat that my colleagues are NOT having this issue although they are running the same code/app and using the same nRF52 DK as the BLE dongle for the BLE App within nRFConnect. Furthermore, there PC is using the same BLE driver. please let me know if you have any other questions.

    Regards,

    Wael
