Changing advertising interval

[Kdcius]

Hi there.

I'm still trying to work on using this ring as an indoor localization system.

I was wondering if any of you guys ever managed to change the adv interval of the ring. It is currently 1000ms which is way too slow for my system sadly. Ideally I would like to set it to 100ms or even less, without any concerns for the battery life :)

Any hint would be appreciated.
Thanks !

@Kdcius You can change the data sampling rate by modifying the ring’s firmware. The firmware can be replaced using the OTA tool provided in this repository, which also includes a higher-frequency firmware version. I have roughly figured out how to modify the sampling rate, and I plan to run a small test to verify it. If it works, I will document the process for changing the firmware sampling rate and upload it to the repository.

Hi @franciumgod
Yep I've seen about the sampling rate :)
However I was talking about the BLE advertising period.
When the ring is not connected it is sending BLE advertising packets every 1000ms and that is not enough for my project (not related to health datas).

I managed to cut trough the ring resin to access the programming pins as ATC did in his videos.
Still trying to manage to properly flash the firmware I built from the SDK but I'm stuck there, something is going wrong with the bootloader I guess...
