Example on setting up esp32 as BLE server?

[dsaul]

I got the answer from someone smart in another group. I was converting Int instead of Float. That’s what works for me:

  on_ble_manufacturer_data_advertise:
    - mac_address: #your MAC address
      manufacturer_id: FFFF
      then:
        - lambda: |-
            float value = *((float*)&x[1]);
            id(ble_sensor).publish_state(value);

Using time, repeating every 10 seconds.
levelmetres = is a template level sensor.
The rest convert the float value to hex chars and updates the manufacturer data, with the values.
To read back convert the values after 0xF9 to float using Little endian.

wasn’t that suggested to you right here?

I did write I understand but didn’t know how to do it, see below.

I understand the concept but Im not sure how to write a lambda code to “convert the values after 0xF9 to float using Little endian.”

Nonetheless, you helped a lot with answers like this:

It tells you in the docs how to set up devices, scan for devices, etc…

Or this:

Have you asked the people in the discord server?

Thanks for pointing out that too, very helpful:

I just really want to thank you for the great help you provided. I didn’t know what I would do without you.

Hopefully my reply helps someone else that is not that good on coding.
