Dis-/Advantage of many or few characteristics

[RootDev4]

Hello everyone,

this is more of a discussion than a question.

I'm wondering what the advantage is of having many characteristics rather than one with all the necessary properties. In my project, my hub station (an ESP32) sends sensor data via a characteristic, logs and errors in different characteristics (all notifiers) and for reading and writing some configurations I added another characteristic. But what is the advantage of this configuration? Why not send and receive all data (e.g. as a stringified JSON object) with only one characteristic?

What's your opinion?

The disadvantage to multiple characteristics is more resources required and more maintenance, the benefit being data segregation. If this is a custom application and isn't required to work within a SIG defined service for compatibility with other BLE devices then absolutely do what makes the most sense for you.
