Data exchange through UART

[Mihail]

I have nRF8001-DK and Arduino Uno. ble_uart_project_template from nRF8001 SDK for Arduino (Bluetooth_low_energy_for_Arduino_0_5_0_0_RC2) was used. It was used with Master Emulator with nRFUart sample code included. By using this template I can send string from nRFUart and recieve this one in Arduino Serial Monitor. How I can add functionality to send string to nRFUart from Arduino Serial Monitor?

And I can't start with ble_uart_project_modify_setup. nRFUart can't discover nRF8001.

Where I can find information how to decipher it ? And why I recieved " Evt Cmd respone: Error. Arduino is in an while(1); loop" ?

ACI Command 0

You can look at the nRF8001 datasheet and interpret the ACI commands and ACI Events. The datasheet is here http://www.nordicsemi.com/eng/Products/Bluetooth-R-low-energy/nRF8001 click on the pdf icon on the right. Sections 24, 25, 26 and 27 have the ACI Commands and Events

C is ACI Command E is ACI Event

C4 means an ACI Command with the length of the packet as 4 bytes. All printing is in hex and can be looked up against the datasheet.

It looks like a ACI command with opcode 0 was sent, which got an error response from the nRF8001. Do you get this often ? Can you put the lib_aci_debug_print(false); and check if you still get the issue. Check your wire lengths and make them shorter.
