Check bluetooth connection before sending data!

Using Arduino Interfacing w/ Software on the Computer

Hi there,

Probably someone has already had this problem, but I couldn't find any topic about this in the forum.

Basically, I'm using an ESP32 to send data via bluetooth to a pc and store the data on an excel spreadsheet using PLX-DAQ. However, before I connect the ESP to the pc, it's already sending data, so this data is lost.
So I want my ESP to check if it's connected before sending data. Could anyone help me?

This sounds like a nonsense scenario which is probably solved with the reset button. There has to be a start point in time and, if the data is being sent before you are ready to receive it, the best solution is not to generate it.

The only way to check for a connection is to send a message and get an expected response.
