Problems with BLE Mesh Example

[Sam]

Good day, I tried the BLE Mesh Example located: devzone.nordicsemi.com/.../

... and for some reason it is not working for me. I posted a comment where the example is posted, but I have not heard back after several days.

I am using one nRF51 dev board, and two nRF51 USB dongles. I did download and install latest J-link software which updated the dev board and dongles. All devices are found within RFConnect (i.e. the device IDs are shown in the "devices to program" window) and I am able to successfully program the official mesh firmware into them just like the example's video (my log matches the video's log). However, when I view RTT-Log I do not get any information... and also the LEDs on the dev board and the dongles are not flashing like they are in example's video. Would someone be able to assist me as to what I have done wrong, as I followed the example exactly multiple times and I cannot get the devices to communicate with one another.

Thanks in advance!

Cheers,

Sam

Hi,

So you get "nRF5-multi-prog: programming completed successfully" in the regular log after you have programmed the device?

In order to start the RTT-log you have to press this button:

.

The LED will first start to blink when RTT is enabled.

Good say Sigurd,

Thank you for your response!

Yes, I do receive the "nRF5-multi-prog: programming completed successfully" message. I even double checked (verified) the programming via mRF Studio... The devices are correctly programmed.

Yes, I pressed the RTT-log button as you indicated... and as I said, I do not get any messages nor does the LED blink (all LEDs simply remain on... no flashing).

Cheers, Sam

All the 4 LEDs on the DK is on? Make sure that you use this firmware.

Good day Sigurd,

Thanks again for your response.

On my nRF51-DK I only have one LED and is on. I have two dongles and their LED are both on. None are flashing, simply solid.

Indeed, the firmware image is the same as what I have programmed. To double check I re-programmed the units with the one you referenced and I see the same issue. Is it possible that the JLink driver is somehow affecting the devices from working? I ask, as the DK and dongle LEDs flash when I remove and reinsert them into the USB ports to the point where Jlink driver loads (i.e. to where i can see the device IDs in the "Devices to Program" list within nRF Connect.

Cheers,

Sam

You only have problem with RTT? Are you able to turn LED1 on/off? Use handle 0x0 and set value to 1 as shown in the video(around 2:20).

What version of J-link do you have? You can download the newest version here.
