BLE SDK - 2 02 01 18
Currently, I am using simple_peripheral example to send ADC data over BLE. I want to convert CHAR2 to a notification property (similar to char4). Program gets compiled successfully and the BLE scanner app also shows N in front of CHAR2 but did not shows the data. Can someone help me to find out the error?
Kindly find the attached code and images for reference.
