I am working on a project with TI CC2541 MCU and I am having major issues with BLE communication with Android. I was wondering what Android app or Windows software can I use to read and write to GATT of CC2541 (I don't have CC dongle)? I have been trying with BLE SensorTag, Sensortag and BlueExplorer on Google Play. The first two seems to be capable of only reading it, while BlueExplorer outputs error each time I try to change any value.
Would it be possible that the cause is any hardware error?

This total depends on what firmware of Z-stack you had loaded into the MCU. Each GATT has a unique message number assigned ( I remember it is something like 4 hex, for example FFFE) only matched number will have proper response. The number from the android side and the number in the firmware must be consistent for a proper communication. I think there are lots more information if you read the Z-stack documentations.
But I am using Bluetooth, not Z-Stack...

It is called BLE-Stack, the look and feel is exactly the same, except the protocol of course.
