802.15.4 and Softdevice Compilation Problem

[Ted Herman]

Hello,

I am trying to use Softdevice and the latest Github version of 802.15.4 support. The make (using linux/armgcc) fails on 

nrf_raal_softdevice.c

because nrf_802154_radio_irq_handler is undefined (implicitly defined) and/or missing. I had thought that by putting some defines into the sdk_config.h that it would be taken care of, so I put these into the sdk_config.h for the make:

// github.com/.../Source-files-and-defines
//
#ifndef RAAL_SINGLE_PHY
#define RAAL_SINGLE_PHY 0
#endif

#ifndef RAAL_SIMULATOR
#define RAAL_SIMULATOR 0
#endif

#ifndef RAAL_SOFTDEVICE
#define RAAL_SOFTDEVICE 1
#endif

#ifndef ENABLE_DEBUG_LOG
#define ENABLE_DEBUG_LOG 0
#endif

#ifndef ENABLE_DEBUG_ASSERT
#define ENABLE_DEBUG_ASSERT 0
#endif

#ifndef ENABLE_DEBUG_GPIO
#define ENABLE_DEBUG_GPIO 0
#endif

#ifndef ENABLE_FEM
#define ENABLE_FEM 0
#endif

#ifndef NRF_802154_INTERNAL_RADIO_IRQ_HANDLING
#define NRF_802154_INTERNAL_RADIO_IRQ_HANDLING 0
#endif

(the last define was needed elsewhere, to get nrf_802154.c to have  nrf_802154_radio_irq_handler in its code).

I might also mention that the names of core components in the page https://github.com/NordicSemiconductor/nRF-IEEE-802.15.4-radio-driver/wiki/Source-files-and-defines seems not to agree with a more recent version of the 802.15.4 code.

Hello,

Here is what I am trying. I copied ble_hrs from the ble_peripherals as the base for the experiment. Then I added statements to initialize 802.15.4 and set the channel (based on another program which successfully used raw transmit of 802.15.4 frames) -- these statements come just after setting up BLE, advertising, etc. Then, in the idle loop, I added a call to a procedures that (raw) transmits a packet. Finally, attempting to get this to compile, the Makefile needed all the core components mentioned in the 802.15.4 wiki, although some of these no longer exist, so I had to improvise by searching the current (cloned a week ago) git repo to attempt a compile. Of course the sdk_config.h needed the extra defines, also mentioned in the wiki. It was unclear whether all of these should be defined 1 or 0, so I defined them to be 1. 

The result of doing all of this is that no matter which way I tried, there was some missing reference to IRQ handling, hence my attempt after studying the code to add that extra define - not mentioned in the wiki.

Going further, I made a new copy of the entire Nordic SDK and forced manually everything to be defined, so it would compile and I could flash it onto an nRF52840. The result, looking at the UART log, was the the very first 802.15.4 transmit raw gets a result of 1 (tx busy), but all subsequent transmits get 0. None of them actually work. I tried digging deeper with debug mode, but I was unable to get JLink and GDB server missing because of a missing so-lib in Linux, even though that very library is present.

Sorry if the above is not specific or accurate in all details. Due to the time difference between us, I do not have access to the equipment and code for some hours. I would appreciate suggestions on how to proceed from here. 

Thank you,

Ted

The sdk_config.h file is not included in the 802.15.4 driver source files, you have to set the defines directly as symbols in the makefile for it to be visible to all files in the project. If you could upload your project, that would really help with being able to debug this issue and see what is happening in your application.

Putting the defines into the Makefile solved the compilation problem, that part is closed. I'm still unable to get the multiprotocol aspect working, After some further experiments, I will post the code.
