nRF8001 no response to Test mode command

[Damian]

Hi, i've just started to use the nRF8001, so forgive me if this is an obvious problem.

i'm using the nRF8001 with a microchip PIC processor. i'm using the ace_tl_demo project to test the hardware. On power-up I receive the deviceStartedEvent (04,81,02). The firmware then sends the test mode command (02,01,02).

Am i correct that the RDYN pin should now go low? And i can then read the SPI response (either deviceStartedEvent or commandResponseEvent)

the RDYN pin never goes low.

Using a logic analyser, i can see that the test mode command is sent ok - sent LSB first

i'd appreciate any idea's/suggestions

regards, Damian

edit:

was a hardware issue, worked ok with the hal_aci_tl_bb file instead of the hal_aci_tl.

I know this is a old post, but since I was facing the same issue trying to port the code to PIC18F, I will give you my 5cents on this question.

My issue was with the SPI mode of PIC, since PIC and Arduino uses different parameters to set them, the table below shows the compatibility for them:

Hope it helps!!
