Running BLE CSC characteristic on ESP32

Postby spasoye » Tue Oct 08, 2019 1:49 pm

Hello guys. Been using ESP32 for some time. Few months ago I decided to try and make my bluetooth bikemeter
(it will measure my speed and cadence). I modified ESP-IDF ble_spp_server serial example. I changed UUID to fit
CSC service UUID and also characteristics UUIDs to fit CSC feature and measurement characteristics. Im using
nRFConnect app to debug the app:

As you can see my device is visible in nrfconnect and it shows data when the data is generated.
But now I wanna see how it behaves in nrftoolbox (or any app that is capable of displaying CSC data).
nRFToolbox does not see my device:

My question is, has anyone ever did something like this (HRM, BPM or any other service), encounterd similar problem?

I am just guessing now, but probably you need to add CSC or other UUID to advertising.
