Hi Magnus

I am having problems on last step when upgrading the bootloader on the Feather (as I got the error messages when pushing the code). Hope you can point me out to some simple procedure, because I cant wrap my head either on Adafruit site or info in YouTube…

Thank you!

Awesome! Thank you for your quick reply

I will be updating here if I find something along the way.

Hi Magnus

I am captured by your design and have started collecting the parts, however I am having problems to locate the IR sensors. Is this an equivalent board I could use? (Hope pasting links works):

Wow, I’ve just sent a message from the future.. :facepalm:

Hola!

Es el trazado exterior supongo ¿Podrías compartir el resultado? (Quizás por PM). Me gustaría probarlo en Cheste en la Volrace.

Gracias!

Thank you for the quick response Harry but something else has to be happening in my case. No other OBD app running on the iPhone and the custom OBD was already deleted but nothing…

I will keep troubleshooting and if possible will collect some logs.

Again, thank you for your support.

Hi Harry I was thinking if reviving this thread instead of opening a new one, decided that keeping the question here, as it’s related, would be maybe beneficial. I have a TONWON OBD2, which supports ELM327 which is recognized as IOS-Vlink but there’s no way I can have it to work with HLT. It appears...

Got the tiny unit today and did some indoors testing, after firmware update and setting using the app it synchronizes now with HLT on 5Hz! So looking forward for the next Trackday. On the previous there was big difference around 3-5kph on the straights with the iPhone internal.

Thanks!
