Research direction

Start by tracing accelerometer event notification handling in the ST BLE Sensor app from the displayed event value to its payload parsing. Compare that parsing with the notification layout sent by Custom_Acceventchar_Send_Notification; done means 0x08 displays as 8 while the timestamp and steps remain correct.

Written by the indexing model from the issue text.

Description

In the firmware I am sending the notification regarding the accelerometer event in this way:
STORE_LE_16(NotifyAccEventCharData, 4000); //TimeStamp
NotifyAccEventCharData[2]=0x08; // Tilt event
STORE_LE_16(NotifyAccEventCharData+3 ,5000); //Steps
Custom_Acceventchar_Send_Notification();
However, in the app (ST BLE Sensor) it shows the accelerometer event type being the value 264 (0x108) instead of 8 (0x08). The TimeStamp and Steps values are displayed correctly. What can I do to fix this problem?

Thanks in advance!
