Forward Navigation Infos via BLE?

[chbla]

Hi there,

I want to get navigation (turn by turn instructions) onto an ESP32 with display.
It's pretty easy with Google Maps and Osmand, using Chronos on Android which forwards the status messages.
There is even a readymade image for various displays: https://espverse.com/missions/chronos-navio

However, I want to use Locus, so I'm curious if there is any way to forward this kind of information.
The ESP32 side can easily be programmed.
Is using the API and creating a custom Android App the only way?

Thank you!
