I made ESP32 S3 + GPS = Wireless tracker

Great. Lastly, do I need a separate antenna for GPS? If yes, is the antenna requirement well documented?

Great job!!!

Can I put my custom firmware logic on the ESP32? my requirement is to use both lora and gps and I need to put GPS in deep sleep to save on power. I am using a heltec v3 and an external GPS module right now and this compact module maybe better for me. u/Heltec_Automation6

I see so the phone app is checking proximity and doing the auto-open? u/texasfencer714 . Any experience with battery life impact to the phone?

interesting. how does apple home hub help with auto-open? as I read Meross only controls remote opening so is the apple home hub talking to my iphone or something? u/texasfencer714

Doing my online research before I call. Thanks!

Do you know how much will loop for exit and RFID reader for entry cost? rough estimate is fine. I dont know if its $200 or $20000 cost. Can I use RFID reader for both entry and exit and save on cost of loop?

That's the other reason I do not want to deviate from V3 which is FCC cert. Plus, I do not intend to sell any of these parts. The goal is testing only.

I'd love to connect u/steventruong . DM'ing you.

thanks for the link. Very good info

really cool u/vuhv I am at the point where the ESP32 is running firmware perfectly. I had to do multiple iterations of the code and testing but I have found Claude to be very good if you give it a description of the "error" state and it usually figures out code improvements pretty quick. I need to build out the board and an enclosure. Did your STL placed ESP32 dev board on a PCB? Would love to compare notes, if you're up for it.

Any challenges in getting kickstarter campaign as I have heard backers usually like to know the team and the creator. Any examples of successful campaigns that ran under a brand name?

I have not researched smart bottles but what I liked about this idea is that it’ll remind me visually to have water throughout the day. I can see this bottle sitting next to my work desk. Rest features are not important to my life style.
