CC2540 USB dongle send/receive

Other Parts Discussed in Thread: CC2540

Hi.

I have switched the USB CC2540 dongle to slave mode with building the HostTestApp, and flashed the hex file into the dongle with the debugger. Now it can communicate with my Galaxy S4 and i can send string with my phone to the dongle without any problems. Now i need to send a string "O\r\n" from the dongle to the phone, and when my phone receive that string, it will send another string back to the dongle. So the dongle must send a string, and receive a string right after.

Q1. Can i make this procedure, while the dongle is in slave mode ?

Q2. How can i send a string with the dongle ?

Thanks in advance

A1: Yes, you can.

A2: You need to send a notification or an indication on an attribute, with the desired value. The phone would notice the value and respond appropriately.

Osman,

I don't know if you can do it in BTool. You'll need to define the attribute before the controller can register to be notified and push notifications out. You can do it in HCI Tester (which is like BTool, but scriptable). The closest example is here: http://processors.wiki.ti.com/index.php/LPRF_BLE_NPGATT
