Glad to hear you found the solution!

Thank you for your help. I was trying with the SDK examples which did not work for me at first. Upon looking further, turns out I had the wrong value of LF crystal capacitors so my LF crystal was not working at all. I switched the softdevice clock source to the internal oscillator and changed the calibration settings accordingly. Everything works fine after that.

Thanks for pointing out that the SDK examples should work out of the box. Otherwise, I would have spent way longer than I should have looking into the software without questioning my hardware.

Thank you so much for the link. It helped me understand a lot about memory allocation. Turns out I was erasing the right area all along. It was a hardware issue that caused my Bluetooth module to not advertise which made me believe I was programming it wrong at first.

[quote user="Duaa"]What does work is <nrfjprog --family NRF52 --program ble_app.hex --verify --chiperase> , no Bluetooth signal detected through [/quote]

Have you verified that the module does work?

[quote user="Duaa"]Is there a special way to use --eraseall to program the firmware? [/quote]

Nope, this is correct from what you describe.

Can you please try the following:

nrfjprog --eraseall
Program <..\[YOUR SDK]\components\softdevice\s132\hex\s132_nrf52_X.X.X_softdevice.hex>
Build and Program <..\[YOUR SDK]\examples\ble_peripheral\ble_app_uart\pca10040\s132\[YOUR COMPILER]\*.hex

Using one of the examples from the SDK should work out of the box. What version of the SoftDevice are you using?

Perhaps application file that you're trying to upload was build to flash into wrong memory area, that overlaps with Softdevice.
It should be like this: https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk52.v0.9.0/ble_app_dfu_memory_52.svg

You can check in Softdevice description its memory boundaries and rebuild application using these memory settings.

You may find this post useful on that matter:

The sequence I've been using so far has been:

First, erase everything:

Then program the softdevice:

Then the firmware:

<nrfjprog --family NRF52 --program ble_app.hex --verify > (does not work, The area to write is not erased)

I tried <nrfjprog --family NRF52 --program ble_app.hex --verify --eraseall> (does not work, ERROR: Two arguments were provided that cannot be combined.)

What does work is <nrfjprog --family NRF52 --program ble_app.hex --verify --chiperase> , no Bluetooth signal detected through

Then:

<nrfjprog --family NRF52 --reset>

Is there a special way to use --eraseall to program the firmware?

Hello,

Have you tried using --eraseall?

Kind regards,
