Hello, where can I find the BLE_GAP.h file or how is it generated and used by nRF8001? Thanks

I am trying to use nRF UART app and nRF8001 chip. But I cannot change the device name. I intend to change the device name after nRF UART app detects the device. Plus when I program the chip, I should be able to put a writeable Device Name.

You should use the nRFgo studio to edit the XML file for the UART over BLE project or the XML file that you are using. The nRFgo studio is available as a free download from the Nordicsemi website

Open the nRFgo studio application File -> Open -> nRF8001 -> Open your XML file. Then go to nRF8001 configuration -> GAP Settings -> Writeable device name -> Check ON the "over the air" and the "From application controller with Pipe".

Save your XML file using File -> Save

Now generate the Service.h file using nRF8001 Setup -> Generate Source files -> Generate only Services.h (Alternately you can run the run_me_compile_xml_to_nRF8001_setup.bat batch file that is present in your application folder)

This will generate a Pipe ( PIPE_GAP_DEVICE_NAME_SET ) in the Services.h file that allows you to set a new device name using the ACI Set local Data message. (lib_aci_set_local_data() function)

An example to use the lib_aci_set_local_data function is present in the UART over BLE example.

David, thanks for your suggestion. But when I opened the XML file with the nRFgo studio I am not able to check the boxes that you have suggested. Plus I am getting the following error. "the given pipe number from assign_pipe was not as expeded. Expected: 3, but got: 2".
