Bringing up the BlueNRG device is failing!

I am using BlueNRG ver 2 device, I'm using not an ST MCU, but freescale's.

SPI was porting to my MCU Kinetis and the issue is:

Instead of getting the ''Blue_Initialized_Event'' (0x04, 0xff, 0x03, 0x01, 0x00, 0x01),

I'm getting (0xff, 0xff, 0xff, 0xff, 0xff, 0xff).

The first 5 bytes SPI are OK and the second 5 bytes are also OK.

(the Bring UP is according to ''Bringing up the BlueNRG and BlueNRG-MS devices'')

attached waveform to describe the SPI signals.

Thanks in advance,

Guy

Dear Guy,

Which bytes are you sending on the SPI header?

The first byte must be 0x0B, which means a read operation.

Instead, if the first byte is 0x0A, this means a write operation.

Best Regards
