Great to hear! Currently, the nrf connect programmer app does not support a merged download of both the softdevice & an application. If you wait around three weeks, the newest nrf connect v2.5.0 update will be available. This nRF Connect together with the v1.0.0-3 experimental Programmer app will be able to do a merged softdevice & application device firmware update (DFU). I have tested this myself & this works very well.

The PCA10056 is quite different from the PCA10059 when it comes to the GPIO pins, etc (even though both use the 52840 SoC). I would recommend taking a look at the ble_app_blinky example from the newest nrf5 sdk. This example works out of the box on the dongle (open the pca10059 example) with nrf connect v2.5.0.

Currently, there is no way to program the dongle via Segger Embedded Studio unfortunately. I would take a look at the differences between the ble_app_blinky example & your example, especially taking a look at the pca10059.h board file.

Some people have managed to program the dongle via a special SWD cable & connected it to the 10 pins on the back of the dongle. The other side of the SWD cable is connected to some kind of JLink programmer (either via a dedicated JLink programmer or via the debug out port on a nRF52 DK). There should be a few devzone questions related to this.

Thanks Bjorn - it works!

I'm using Segger embedded studio (using the PCA10056). Can you recommend the best way to upload my program to the dongle?

Thanks again,

Daniel

Hi Daniel,

Got a hold of a v1.0.0 52840 dongle. I had none of the issues you describe. The dongle was in bootloader mode when I attached it to my laptop, then nrf connect ble v2.2.0 asked to update the connectivity fw, I said yes & the dongle was connected to successfully. I can successfully scan for other BLE devices in the vicinity.

Below is a copy of the log from the nrf connect application:

Could you please put the dongle in bootloader mode by attaching the dongle to the computer & pressing the reset button on the dongle (not the big white one, but the smaller one that is angled perpendicular to SW1). Then, open the bluetooth low energy application again & redownload the connectivity FW.

Kind Regards,

Bjørn

Hi Daniel,

You are using nrf connect version 2.4.0 with the bluetooth low energy official v2.2.0 app, right? I have tested the 52840 dongle v0.6.0 on nrf connect & it worked like a charm. I will see if I can get a hold of a v1.0.0 dongle to test with & let you know if I can replicate your error.

Kind Regards,

Bjørn

Bjorn,

Yes, I followed the instructions at the link you provided; the red light is off (if I remember correctly, it was turned off as I followed the instructions); the dongle is directly connected to the pc; version is 1.0.0

Best regards,

Daniel

Hi Daniel,

Have you taken a look at the documentation provided here? Which nrf connect version are you currently using? Is the dongle in bootloader mode (i.e. is the red LED pulsing) when you connect it to your pc? Are you by any chance using a usb hub or docking station or are you attaching the dongle directly to the usb input? Which version of the dongle do you have? You can check this by reading what it says under the line PCA10059 on the white sticker on the back of the dongle (e.g. 0.6.0).

Kind Regards,

Bjørn
