Sending sensor data via BLE

P-Nucleo STM32WB55

I have two 3-axis accelerometers & toe temperature sensors on an I2C bus. I taking measurements at 1 Hz.

I would like to send this data over BLE. Every tutorial so far seems to skip how to read the data into a characteristic & then send it. At this point I am only interested in broadcasting.

I've managed to set up an attribute for reading, given the service its names. I can see the device & the service advertised on my phone via ST's BLE app. So how do I get the data into the service?

I'm going around in circles here!!

Please no "have you looked at the examples", yes I have they aren't making any sense to me, I need to talk to a human about this.
