Use of BT_app_send() function in PAN1315 mindtree stack

Hi,

I'm desining an interface use the PAN1315 module, and now I have a question about the data send spi. Currently I'm changing the code from the temperature sensor application, and after successfully establish the bluetooth connection between the PAN1315 and a computer side bluetooth COM port, I simply change the data in appl_spp_data_buffer[] and then use the function sdk_menu_selection_handler(OP_PEER_DATASEND) to send data. However, everytime I call this function, it will send the data continuously, while what I want is just send the data one time. I notice there is a function build in the sdk.c, called BT_spp_send(),   but I don't know how to use this one. It seems the first parameter is called remote device index,but I don't know what is that......

Has anyone meet problems like this one before? Do you have some suggestions about how to send data just one time? Thanks so much.

    SuiYu,

    You will need to work within the framework of FreeRTOS to send your data. From experience, BT_spp_send() cannot be freely called as you think. Please take a look at the following wiki that has an example on modifying the MT demo to send data by adding more tasks:

    http://processors.wiki.ti.com/index.php/CC256x_MT_UART_BRIDGE

    remote device index is a number of the device you're connected to. Since normally you're always connected to 1 device, this number can be 0.
