Hello Roman,

There is both RX and TX functionality, but it's complicated.

For 2.4GHz, there is both RX and TX, but you can disable TX and just use RX scan. Then there no need to do TX testing as long as you never intend to use TX. You have to configure the nRF7000 to not use TX for this to be true.

For 5GHz it is only passive scan, no TX.

Hi Asbjørn may you help me with this question:

[quote userid="122854" url="~/f/nordic-q-a/125964/radio-testing-configuration/556280"]

We use the nRF7000, which is only a Wi-Fi scanning chip. Does it even require TX testing, and is TX testing actually possible on this chip?

Hey Asbjørn thanks a lot with BT everything's clear.

For Wi-Fi I need a bit more time. As I understand it, the commands I need to use are:

wifi_radio_test init 1
wifi_radio_test tx_pkt_rate 12
wifi_radio_test tx_pkt_len 4000
wifi_radio_test tx_power 10
wifi_radio_test tx_pkt_gap 4200
wifi_radio_test set_edge_bo 3
wifi_radio_test set_ant_gain 2
wifi_radio_test tx 1

I only need to figure out which of these are actually relevant for our application.

Also, one additional point because I am a bit confused:
We use the nRF7000, which is only a Wi-Fi scanning chip. Does it even require TX testing, and is TX testing actually possible on this chip?

Hello Roman,

For BLE:

Start channel: 02, 40 and 80 would be low, mid and high.

Output power: Set it to the highest your application will use. For nRF52832 it would be 0dBm presumably.

start_tx_modulated carrier to start continuous transmission. You might want to set the transmit_pattern as well to make it even between 0 and 1 across a payload.

For Wifi:

Bit more complicated, but the following two links should be useful. The first one I assume you've been to already since you've built the example.

https://docs.nordicsemi.com/bundle/ncs-2.9.0/page/nrf/samples/wifi/radio_test/sample_description.html

and

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/protocols/wifi/regulatory_certification/index.html

wifi_radio_test init 1, 7 and 14 would be the low, mid and high.

Adjust the tx_power to be what you have available in your application.

Consider the edge backoff as well if you are using the highest output power modes with PA.

Best regards

Asbjørn
