I am having trouble discovering GATT attribute handles. I have my iPhone setup as a peripheral with some sample code provided by Apple. I have attached it for reference as well as my BGScript source code. I am able to connect successfully to the iPhone using the command:

call gap_connect_direct(bdaddr(0:6), 1, 80, 80, 500, 0)(result, connection_handle)

I have then been trying to get several find information functions to return a result of 0, with absolutely no success. I have tried all of the following commands with no success.

call attclient_find_information(connection_handle, $0000, $ffff)(connection, result)

I also tried this one with various different start and end values. Including the ones that I am able to see with a scanner I have.

call attclient_read_by_handle(connection_handle, $1)(connection, result)

I tried this with all the handles I was able to see with my scanner.

Any ideas? I am pretty new to all of this so I apologize if I am missing something simple here.
