DTM LE_TEST_END Command Error

[maseth0]

I've been tested for BT SIG however have met error which sent 0xc000 and got 0xc000. I expected to receive 0x8xxx. Command is LE_TEST_END in DTM.

I tested with nRF52832 custom board.

Hi,

 

If I understand correctly, what happens is

1. Tester sends 0xC000 
2. DUT sends 0xC000

and you expect

1. Tester sends 0xC000
2. DUT sends 0x8000

as the first sequence causes an error in the tester? Do you have logic analyzer traces that you can share? Which test has been run prior to the error?

 

Best regards,

Andreas

Hey,

Yes thats right.

We try to do the DTM test with some testsoftware from 7Layers to prepare the SIG test.

The transmit and receive test are okay. They have both a "green" status. Because of the answer from the DUT the tester is "red" for LED_TEST_END. 

Best regards,

Hi,

 

Testsoftware from 7layers: is this software for your PC or for the DUT? What does your setup look like?

 

Have you tried using a nRF52 DK, cutting SB9 (power to the nRF52 on the DK) or SB14+SB16 (UART to the nRF52 on the DK) and running P0.06 and P0.08 from the header on the DK to your custom board? You can then use nRFgo Studio to test that it works.

UART can be a little finicky get to work, have you scoped the UART lines and seen that he right commands are actually received at the nRF52?

 

Best regards,
