Adjusting the radio examples to be compliant with IEEE 802.15.4

[NewtoM]

Hi!

I would like to send and receive IEEE 802.15.4 compliant packages in a very simple way (no ACK, no routing, just raw data transmitted). For the simplicity of the task at hand I would not prefer using the pre-compiled IEEE 802.15.4 library, nor the nRF-IEEE-802.15.4-radio-driver, but just use some low level calls. Unfortunately, it seems there is no HAL or driver module in SDK v15 for radio, so I need to use register access to configure the radio.

I had a look at Radio Transmitter example and Radio Receiver example, and they are close to that what I need. I am just a bit unsure how to change them to be compliant with 802.15.4. For any help on that I would be very grateful.

Thanks,
Tamas

HI Tamas, 

I apologize for the slow response.

You could take a look at this answer, there should be some attached code that sends 802.15.4 compliant packets using the RADIO registers directly. 

Best regards

Hi Bjørn,

Can you better explain how to modify the Radio Trasmitter example and the Radio Receiver example?

If I have correctly understood, the linked post is treating only the trasmitter. What about the receiver? I am currently able to transmit with 802.15.4 only changing the "NRF_RADIO->MODE" in "RADIO_MODE_MODE_Ieee802154_250Kbit", but I am not sure that it is the correct way to implement it.

Thanks

Hi Pietro,

last year I worked on a Nordic nRF52840 port of OpenWSN. Although it had some bugs, the 802.15.4 radio part worked kind of well. You will find the source for the radio initialization here: https://github.com/tharczos/openwsn-fw_FW-751/blob/develop/bsp/boards/nrf52840/radio.c , maybe it helps.

Best,
Tamas

HI,I have used this openwsn-nrf52840DK project, and I have some questions about this project. In the file (openwsn-fw_FW881/bsp/boards/uart.c),why you did not use app_uart_init() function to initiate the UART and configure the UART by GPIO. I also want to know how to configure UART1 to receive the data from my board.
