I'm using nRF Connect version 4.22.3 on both devices.
I do not have a nRF51 och 52.
I noticed the isse developing a program for the ESP32 using esp idf.
But I have the same issue with any other sensor, Polar H7, Cadense etc..
I'm not running Auto service discovery.
Hello,
Automatic service discovery is enabled by default. If disabled, in Settings -> Connectivity -> Automatic service discovery, you need to initiate service discovery manually, by selecting the menu in top right corner and choosing Discover Services.
