Range Test 802.15.4 radio

[KnutS]

I'm looking for a nodified 'Wireless UART example" that I can use for a range test.

https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/wireless_uart_15_4.html

At one side I can connect a PC with a UART, but on the other side I have only the nRF52840DK wit a battery pack. With this example I need 2 UARTs connected.

The LED's from the example will be sufficient for a test, that the second board sends the received packets back to the first board.

The output of 8dBm is needed to test the maximum range.

Thanks

Knut

Hi.

For a simple range test, use this firmware as transmitter: transmitter.hex

The UART interface for the transmitter uses 8N1, baudrate 115200

Commands you need:

Transmit frame:
transmit on 4198030405060708090a0b0c0d0e0f

Set TX power:
tx_power 8

Select channel:
channel 19

For receiver, flash this file:

receiver_dk.hex

----------------------------------------------------------------------------------------

Testing:

First, set channel to 19 since the receiver is hardcoded to channel 19.

Second, set the tx power to your desired level with tx_power.

Send frames by pasting transmit on 4198030405060708090a0b0c0d0e0f

You will see that LED4 on the DK will toggle when it receives a packet

I captured the packets in Wireshark to make sure that it works:

Best regards,

Andreas
