RN4870 SPI

Hi,
 
I have a RN4870 PICtail development board and I would like to use the SPI to communication with an accelerometer.
However, when I enter command mode and try to initialize the SPI, I get an error. Anyone have an idea why this might be?
 
I've tried the following commands to initialize (all to no avail):
{A,0,2,05
{A,0,4,05
{A,3,2,05
{A,3,4,05
 
I've tried with different firmware version as well, including 1.28, 1.30 and 1.40. And I still can't get it to work.
