Displaying Mesh Data with Nordic Thingy 52 in Bluetooth Mesh Network

[The Boon]

Dear Nordic Tech Support and Developers,

Hello. I have implemented the Mesh Demo (light switch example) with Nordic Thingy 52. I would like to inquire an info on the side of hardware.

I always receive my information (RSSI, time) via connection of a J-Link during the debug mode of the mesh demo. To make the demo more presentable, I would like to have the data displayed on a display which is connected to the thingy 52. For instance, the data about whether a node which originally belonged in the mesh network is missing or out of range.

Had anyone connect thingy 52 with a display (e.g. a smart LCD with BLE) before? Which cable is suitable for the communication between thingy (e.g. PIN 0.02 and GND?) and the display? From the side of codes programming, is it possible that the transmitting data in the mesh network to be passed on to the display and how is it done?

I am sorry for the long questions. I would be very thankful for any insights that I could receive. Thank you!

Best regards,

Hi,

I had tested with PicoScope Oscilloscope software (logic analyzer) for the three pairs of external SCL and SDA pins (P4, P5 and P7). It didn't managed to detect signal coming out from thingy. Had I perhaps miss out something? :/

Regarding your questions, I think it would clearly be the easiest to use a 52 DK or a 52840 DK. Code has already been written for the adafruit touch display I mentioned & it should work out of the box with the multilink demo. In addition, the DK is directly compatible with this display. Should not be too difficult to update this for the mesh (link 1, link 2).

If you really want to use the Thingy, there is a possibility to add a display to that & we have done this previously. However, it is trickier to get this to work.

Hi Bjorn,

Have you done this previously with the Thingys? Is there a link to the work or some guidelines for that? Thanks!

Best,

The Boon

Besides, I would gladly share the parcel of my code here if it helps you understand better. :)

Hi Bjorn,

I have a short favor to ask for. I am not sure whether should I open a new ticket for this:

For the nrf52 BLE multi link multi role project that you've sent me, could I have the source code for the android app?

Thanks for your concern.

Best regards,
