i used tool to write the s140_nrf52_6.1.0_softdevice.hex and nrf52840_xxaa.hex(from example ) to NRF52832 by nrf connect  as above

then i reset the board, but i can not scan the ble advertsing by the nrf connect on the phone. I think the chip is not working

then i use keil to debug the board、

it is working and start to advertisiing、

but the keil IDE give information as follow when i can use nrf connect on phone to connect the board。

    Hi

    First off, I see that you say you're flashing the S140 SoftDevice and an nRF52840 application onto an nRF52832, which would cause issues as the nRF52832 has less RAM and Flash memory than an nRF52840, so an application and the S140 SoftDevice might exceed the memory of the nRF52832. You need to use the S132 and an application made for the nRF52832 to ensure correct operation.

    Can you also share some information on what example application this nrf52840_xxaa.hex is based on?

    Best regards,

    Simon

    thank u for reply、

    i wrote the wrong type.

    actually i use NRF 52840.

    the example is \examples\ble_peripheral\ble_app_uart\pca10056\s140\arm5_no_packs

    today i tried the new SDK nRF5_SDK_17.1.0_ddde560

    i just compile the project to produce the nrf52840_xxaa.hex。

    i use nrf connect for desktop 3.9.1 to write the \components\softdevice\s140\hex\s140_nrf52_7.2.0_softdevice.hex & nrf52840_xxaa.hex to the board。as  follow

    i power again the board。it is still not work。

    and debug has the same trouble as what i said as the title

    and i want to mention that i use a third party board（RF-BM-ND06） installed with NRF52840

    circuit is as follow

    pls give some advice。

    best regards
