Ready-to-use binary #8

Closed konradorlinski closed 1 year ago

konradorlinski commented 1 year ago

Hi!

The project looks really promising, and I would love to test it out, but I don't have experience with compiling these types of projects. I tried installing Keil uVision, but after wasting several hours without success, I decided to ask here for a ready-to-use binary file. Would anyone be able to share the compiled firmware? I can handle the flashing process myself.

Thank you in advance for your help!

Also have a look at this: https://github.com/biemster/st17h66_RF although you'll need to implement the proper FindMy broadcast yourself (which is not hard, just use this repo as example), but it compiles with GCC. The plan is to make that repo the default and do away with Keil altogether, but I did not get to that yet.

I'm confusing myself with all the FindMy repos I made, you actually should use this: https://github.com/biemster/FindMy/tree/main/Lenze_ST17H66

Although that might not have been optimized for low power, have a look at issue #7 (LONG thread, but has a solution at the end)

Thanks for your help! I admit I missed that binary file in the repository. I'll try uploading it and will get back to you if I have any problems.

konradorlinski commented 1 year ago

I tried to upload this binary using Lenze Flasher as well as your and vadimkozhin script in Python. After supposedly uploading correctly (no errors, communication with MCU proceeds correctly) nothing happens with the tag.

My hardware: Typical iTAG eg. Photo

Once uploaded, it should automatically be detected on the phone or do I need to do something else? Can you advise me to help?

biemster commented 1 year ago

The tag should then start sending out the FindMy advertisement. You could check that with a bluetooth sniffer like nRF Connect on your phone.

I did some more research on my problem and it appears that I am doing everything correctly. The tag with the default key broadcasts at: D1:22:33:44:55:66, (which agrees with the source code) and when I upload it with a generated key (Advertisement key) it appears under a different one (I found this by the distance in the BLE Scanner application and disconnecting the tag's power supply).

I'm just wondering if I'm making a wrong assumption - should a tag programmed this way appear to be added in the Find My app on the iPhone or not? I recently bought a tag from aliexpress, which fully cooperate with Find My (it appears in the Find My app on the iPhone), and hence my question about the app on the phone. The tag is based on the ST17H65B processor.

I found the answer to my question: https://github.com/seemoo-lab/openhaystack/issues/39
