I am creating an application to work with the JDY-23 BLE module. I need to transmit a word from a smartphone to a terminal. The connection is established, but during transmission the message "Service fda50693-a4e2-4fb1-afcf-c6eb07647825, characteristic fda50693-a4e2-4fb1-afcf-c6eb07647825 are not published by the connected device." What am I doing wrong? Please help.
Not familiar with this module - what microcontroller are you using with it (Make, Model, Version)? Did you find instructions on how to connect the module to the microcontroller?
The Script (known as a Sketch if the microcontroller is an Arduino) that drives the BLE communication should include UUIDs for that communication and they must of course be identical to those in your App.
