Nazmie Razali asked 6 years ago

Hi, right now I’m trying to figure out about the BLE on ESP32 and I’m using Heltec WIFI Lora 32 as my kit. But I’m kind of stuck at your Module 5 Unit 3, in Bluetooth UUID section. Can you explain to me how you got all those UUID including UUID for descriptor and characteristics? Hope to hear from you soon, thank you.

Hi Nazmie, you can use this website https://www.uuidgenerator.net/ to generate random UUIDs… They just need to be unique in your different projects.

For testing purposes, you can use the UUIDs provided in the course, but if you end up using more boards running at the same, you should generate different UUIDs.

I hope that helps.

Regards.
