Hello everyone,
I want to establish serial communication between 3 nRF52840 dongles using mesh.
Can you suggest me the steps from begining. Also i have read the documentation blog of nordic semiconductor.
I have downloaded nrf sdk for mesh version 2.1 and nrf sdk for mesh version 15. After this tell me how to implement the examples on multiple dongles.
Also i have downloaded nrf connect for pc.
Hi,
Do you by any chance have a nRF52 dev kit too? I have gotten the light switch server example to work on the dongle, but only when it is programmed via a dev kit & connected to the dev kit via a SWD cable, like shown below:
I will continue to take a look at why the dongle is not being provisioned when only attached to the usb port. I suspect it has something to do with Segger RTT. I used a 52832 dev kit as the provisioner & one for the client example & the 52840 dongle was the light switch server. I was successfully able to send messages over the mesh network from the client to the dongle server.
Is it correct that you want to provision the mesh network via the nRF Mesh application for Android/iOS? Do you want to have one light switch client & two light switch servers for example?
I believe you will still need to have the dongle connected to a usb port when you are running the mesh. As you can see from the main product page for the dongle, there is no debug support. Since there is no Segger chip on the dongle, there is no segger rtt for logging like it is done in the mesh sdk using a nrf52 dev kit. This is the reason that I have soldered on a 10 pin adapter to the P1 port on the dongle. The 10 pin SWD cable is attached to the debug out port on the 52 dev kit. The dev kit, as you most likely know, has a segger chip & therefore you can debug the dongle via the dev kit.
It should still be possible to set up a mesh network using only dongles, but you would most likely require some dev kits to act as a debugging interface to the dongles. Like I mentioned before, I have gotten the client & server to work on the dongle when the dongle is connected via the dev kit. The dongle does not currently work out of the box when only attached to the usb port (no 10 pin cable attached). I am still trying to figure out why this is the case. I will update the thread when I have any updates.
Here are two pictures of the connection:
If you take a look at sdk 15.1 & search for pca10059 in the examples folder, you can find examples that will work out of the box with the dongle.
Kind Regards,
Bjørn
