Thingy:52 Edge Impulse data forwarder with nRF52840 Dongle PCA10059

[Haroldo]

Is that possible use the nRF52840 Dongle PCA10059 with CENTRAL_UART to connect theThingy:52 to forwarding data to Edge Impulse studio?

Hey Haraldo!

Just letting you know that I am looking into it, but I will have to get back to you over the weekend.

Best regards,

Elfving

Ok Elfving!

I wating you over the weekend.

Thanks

Hey Haraldo!

Yes, that is very much possible. I assume you have taken a look at the tutorials on the developer page about this.

The main issue with the dongle is that it isn't as easy to work with as a DK, since it doesn't have an onboard debugger. Using a dongle shouldn't be any less feasible than a DK however.

Best regards,

Hi Elfving,

I programmed the nRF52840 Dongle with CENTRAL_UART firmware and the board connected to Thingy: 52 (the red led flashes fast), but I can't forward the data to Edge Impulse Studio.

In the command window:

C:\Users\harol>edge-impulse-data-forwarder
Edge Impulse data forwarder v1.13.15
Endpoints:
    Websocket: wss://remote-mgmt.edgeimpulse.com
    API:       https://studio.edgeimpulse.com/v1
    Ingestion: https://ingestion.edgeimpulse.com

Dongle does not connect to serial UART.

I don't know what I'm doing wrong.

Hey again Haraldo!

Ah right, I forgot that the data forwarding example uses the COM port. It is sadly true that for that to work right out of the box you would need a DK. Sorry about that.

It is possible to get it to work on the dongle by using the USB connection as a COM port, but that would require a bit of work, which is yet another reason to get a DK (as the DK has an external debugger, and easier to work with).

Best regards,

Elfving
