How can I get data and save to file using BTOOL when sending data from several BLE peripherals to BLE central periodically?

As I know, BTool doesn't have capability to save received data to a file. The alternative is to copy the contents in the message window and save it to a text file.

You can just right click on the BTOOL log, and there is an option save. Then you can save the whole log to file, but it will be a bit messy.

thank YiKai and Christin
Notification is used to pass data from peripharals(sensors), I cann't see sensor data received in the message window, do I need to enable notification on BTOOL? how to do this?

Which peripheral example do you use?

Our peripheral consists of cc2540+cpu+sensor, cpu handle sampled data and send to cc2540 via UART, then up-send data to central via 2540 BLE periodically. I use app BT SW to get data only when 1 to 1 and not support 1 to multi, so I want to use BTOOL to get data for analysis for 1 to multi.

Try to refer to processors.wiki.ti.com/.../LPRF_BLE_Simple_Application

This problem was solved, I misuse charicteristic handle value marked by figure in application, this handle value should be handle value read+1. Thank you a lot YiKai.

You are welcome and it's good to know it works now.

Yikai,
Here we are reading data using BTOOL. same thing i want to do using another device.
But not able to understand how to select the read by UUID function.
