I want to use my phone to send HR data to my cycling head unit over BLE. I have written an app on my phone which sends the data as a heart rate monitor. However, there is a difference since smartphones are using resolvable private addresses for privacy reasons. The privacy feature require BLE 4.2 as written in the Bluetooth Core specification.
I tried to pair my phone with the head unit, it is detected as a HRM but then it never connects. I think this may be because an IRK (resolving identity key). Are X30 Edge units compatible with BLE 4.2?
Then I tried with Jim's BLE scanner Connect IQ app. My device get found (advertising data is recveived), but then I am unable to connect as well. Does anyone have an idea about how I could proceed to connect my phone to my GPS over BLE?
Thank you very much
