From where to download the pre-install edge impulse .hex on thingy53

[Sachin Rawat]

Hi,

I am in trouble, I have a thingy53 which I previously used as a Bluetooth peripheral, but now my needs are changed and I need to use edge impulse on it.

But the problem is I don't have the pre-installed edge impulse(which is already flashed on the board when shipped), and now, I tried very hard but edge impulse is not working on it.

I have used multiple samples provided by nordic like **Machine Learning Application** so that the daemon accepted it but unfortunately, it only needs that already pre-flashed new board.

I am following this official link:- docs.edgeimpulse.com/.../nordic-semi-thingy53

I have used the DFU.zip from step 2, but it is still not working.

Now, my humble request for you is, can you please provide me with the dfu/hex of that which is pre-installed in the board when shipped?

NCS version 1.9.1

IDK if this is helpful for you, but when I use the machine learning application, then it shows the deviceID error

Hi, 

You could download the precompiled image here. Please also check the Getting started with precompiled firmware samples documentation.

Hi 
Thanks for your reply
I have test with the precompiled firmware downloaded from the above link, I have flashed 2 different firmware

1. Edge Impulse: But with this firmware nor the Bluetooth is advertising nor, the daemon is recognising this board.

2. Machine Learning: This is advertising it's name but the daemon is not recognizing it as a edge impulse code

Wrapping up all suggestions, I think the machine learning sample from the nrf/application directory is useful for connecting board with edge impulse studio, as that sample is working on accelerometer and working fine on local board, but when I tried to connect it with the edge ipulse studio with the command edge-impulse-daemon , it is somewhat working but also failed with authenticate error which you can see on below screenshot.

Do you have any suggestion?
Am I using the correct sample for connecting to edge_impulse_studio?

Help me to overcome this error...

How do you program the thingy53? It may take one minute to boot up with the new image.

Are you able to use the nRF Edge Impulse mobile application to connect over Bluetooth LE? You could follow the instructions in the Nordic Semi Thingy:53 page.

I am not familiar with the Edge Impulse Studio. You could seek help on https://forum.edgeimpulse.com/

I have programmed it with both the method, by connecting it with nrf5340dk as a debugger and then flashing through VS code, and by directly connecting thingy53 with the programmer app

I tried it, but facing some problem

1. When using the pre-compiled edge impulse code which I downloaded from the above link, as I said to you already, it is not advertising its name which is why the app is not able to scan it.

2.When I use the Machine learning sample having at location ncs/application, then in that case the board is advertising itself with the name "edge impulse" but the edge impulse mobile app is not recognising it and so not showing up its name on it.

Thanks, I am contacting them also but as you know machine learning sample is a Nordic sample so it is better to ask you guys about this.
