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

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

Thank you Andreas,

can you check the transmitter file please. The receiver file is programmed.

I get the error message.

Could not open HEX file: Error: Malformed hex file: Could not parse between characters 44 and 46 ("")

Thanks for your fast reply

Hi.

Could you please program it with nrfjprog, I don't know why this error shows up in nRF Connect Programmer.

Best regards,

Andreas

Hi again.

I've talked to your FAE and gotten more details about what you asked about.

I've made an application that should be suitable now, for next time, please include this details in the DevZone tickets as DevZone is preferred communication channel for support.

Transmitter: transmitter_with_button_8dbm.hex

Press button 1 to start transmitting, press button 2 to stop transmitting. While transmitting LED 1 will be on.

The receiver is the same as last time: receiver_dk.hex

LED 4 will switch state when a packet is received.

Best regards,

Andreas

Thank you very much. It's working now, also with nRF Connect programmer.

Can you send also the whole project files, that customer can modify this.

Best regards

Knut
