Android Question BLE2 Help Please!

[seskindell]

Hi ... I finally got the app to read the UUID strings that need to turn on the accelerometer and then
read the x,y,z coordinates in real time.

I found a great app in the play store for finding out information regarding the UUID's.
The app is called "nRF Connect". I found it can read values even if the current device is bonded/paired.

This is the current information I found for the UUID's for my device OLP425-7539 which is a small
battery operated u-blox sensor. Any help in how I can read the x,y,z coordinates and how to turn the accel. on would be greatly appreciated!!!
