Hardware: Pair with Bluetooth, not be dependent on Wi-fi

[adamcohenhillel]

Currently it is using Wi-Fi, which makes it not-so mobile (you can technically connect it to your phone hot-spot).

An alternative approach would either be:

• Bluetooth pairing with the mobile device
• Sdd a 4G card that will allow it to be completely independent

@adamcohenhillel I am working on this for esp32

[adamcohenhillel]

@Krupskis that is great, assigned the ticket to you then.

Have you been able to run on the esp32 at the end? just started playing with mine yday

[Krupskis]

Yes, got the bluetooth and mic working separately. Trying to put it all together. The mic is weird tho, I get a bit pitched sound.

@Krupskis anything I can help with? if you want, you can share the code and I will try to debug the sound stuff

This is a super cool project!
Looking at the bluetooth implementation, it seems the plan is to live stream audio from the device to a phone over bluetooth. So, how is that different from just using a simple bluetooth microphone ($3/$4 on aliexpress)?
I think the main selling point of Pendant and Tag is that they work by themselves, and then periodically upload to the cloud.
Since most microcontrollers won't have a lot of memory, you could use an SD card to store the audio, and when bluetooth or wifi is available upload it to supabase.
wdyt?
