SPI Packet

[user123x]

I want to use ATMEGA 328 to send a packet over to the chip as follows:

SPDR = packet ;

Can some one kindly post what the content of this packat should be ? is it possible to transfer a 32 Byte packet in this way to the BLE chip ?

Thanks in advance for you support. Any sample application code for this would be much appriciated.

Hi,

If you want to interface with the nRF8001, you may want to have a look in the nRF8001 spec. Chapter 7 Interfaces, and from chapter 18 to 27 are important to know how it works (how to interface your MCU with nRF8001).

It's actually good idea to follow what we do in the Arduino SDK as Awneil pointed out.

We also provided the SDK for nRF8001 but using our own MCU (nRF8200). It may not as similar to Atmel chip as the Arduino

I have read the entire documentation. However I still dont have a sample packet. How should it be coded can you give an example. What does this packet look like . Lets say it has 3 bytes:

LEN : ECHO: DATA 0x03 0x02 0x01

How do I send it via SPI line ?
