Need your expertise on our customer's query. Posting on their behalf:
I am using CC2652RB for my development project. But i am facing challenge in transferring Text file data to GATT client via BLE. As a beginning step, I'm trying to develop on project zero sample code and i have completed all steps of the Bluetooth low energy Custom Profile tutorial on this link dev.ti.com/.../ble_01_custom_profile.html
However I am not able to verify the functionality of Task 5 image attached. On pressing button the initial value is not getting updated as mentioned in the step 4 of task 5. Please refer to the attached image.
Can you help me where I need to make changes in project zero sample code to transfer data from GATT server (CC2652RB launchpad) to GATT client (Android smart phone) via BLE after a button push as suggested in the link?
Right now what is happening is, I will first write some data from android phone in the sunlight service characteristic and then after a button press I am able to read data on the sunlight service characteristic.
My question is why the initial value is not getting updated as I have called sunlight service set parameter function in handle button press and second is i just want keep updating it every time button is pressed but its stuck at the initial value.
Please also refer the attached PDF file for my current state of task. Thanks in advance!
