IEEE 802.15.4 PHY test tool only NO ACK response

[k.szpila]

Hi,

I'm trying to run `samples/peripheral/802154_phy_test` sample to perform some range tests

My setup:

- nrf55840 dev kit,
- nrf5340 Audio dev kit,
- nRF Connect SDK 2.5.99,

I configure one board as CMD device and try to start test with following commands:

custom changemode 1
custom rstart
custom lsetpayload 5 FFFFFFFFFF
custom ltx 10 1000

But, i got error on every message:

NO ACK
[00:39:00.788,696] <inf> rf_proc: tx failed error 5!
NO ACK
[00:39:01.790,435] <inf> rf_proc: tx failed error 5!

[00:39:09.805,023] <inf> rf_proc: tx failed error 5!  

When i use commands `custom find` and `custom rping` i'm able to get a proper response.

What am I missing? Is this configuration correct?

Hi,

I see the same when I test. I do not find any other examples of this feature (custom ltx) being used, and there may be an issue here. That said, for range testing you can also check if there is communication by using "custom rping" or even just repeatedly issuing "custom find".
