The GCC compiler version was my problem. Thank you for your help.

There are 2 problems:

first use the GCC toolchain version 4.9 2015q3 instead of 7 2017-q4-major (if someone knows this reason please to explain me it)
in the file {NRF52 SDK 13.0.0}/libraries/bootloader/ble_dfu/nrf_ble_dfu.c in the function advertising_stop(): replace "m_flags |= DFU_BLE_FLAG_IS_ADVERTISING;" by "m_flags &= ~DFU_BLE_FLAG_IS_ADVERTISING;"

Could you use the sniffer and check what happens when you click connect on the phone ?

On the nRF52832, could you debug and check if there is a BLE_GAP_EVT_CONNECTED event ? And then if there is, if the DISCONNECTED event comes after and with which disconnect reason ?

Also, when you use gcc, please make sure you use the suggested gcc version . Have a look here:

But my problem as specified in my question still present (error on bin file generated by GCC through its makefile whereas Keil is OK)

I run nrf sniffer and I resolve one problem: into the stop_advertising function a data is not correctly cleared.

Please make sure you use Jlink v16.6C. You may need to replace the firmware on the board with that version. To downgrade, you can Jlink Configurator, right click on the board and select replace firmware.

If the issue remains, please take a screenshot and update the question.

The device is not in the list. For the nrf sniffer I work on Wireshark v2.4.4. I see my nrf Sniffer but impossible to view any packet on the BLE. Can you help me please?

You read the manual. There is a documentation for the sniffer v2.

If you see the device in the list of Bluetooth device in Bluetooth setting, then they are bonded. You can remove bond information and click the device and select "Forget this device".

I don't know if I use bonding between my phone and the device (I use just as default parameter). How do you do to use nRF Sniffer when the v1 has the executable and the v2 update files to use PCA10040?

Do you use bonding between the phone and the device ? Make sure you delete bonding on the phone before you test.

What do you mean by you can't use nRFSniffer ? If you have one extra PCA10040 you can use it as the sniffer.

Hi,

I can't use nRF Sniffer.

My problem is that when the application received on ble_dfu service the case BLE_DFU_EVT_ENTERING_BOOTLOADER I disable current connection (sd_ble_gap_disconnect then ble_conn_params_stop then pm_peers_delete) then the target enters in bootloader mode. But in bootloader mode the connection failed with the mobile which tries to send new application and the target re-enters in old application.

Hi,

You are telling that you can see the advertising packet, but you can't connect. What exactly happened when you tried to connect ? Do you have any log from nRFConnect ? Please make sure you erase bond information on the phone.

I would suggest to use our sniffer and capture a sniffer trace.
