Smartphone BLE Beacon

Hi.

I have some BLE Gateways (ESP8266 + NRF51822) that transmits beacon info through MQTT. My sensors are also NRF51822.

What I’m now trying to achieve now is to use our smartphones, Samsung Android, for room presence detection.
Samsung phone --> BLE Gateway --> Pi --> Home Assistant.
I’m having trouble getting our phones to do BLE transmissions. Has anyone succeeded with this?

Hi
Did you have any luck on this ?

Esp32 + OpenMQTT seems to work, although I haven’t spent too much time testing it yet. Phone running BLE beacon app, set to transmit.
