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

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
@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
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?
