Issue with hello_dect sample using DECT NR+ FW v1.1.0

sgordon291

Nordic TS,

I've installed and begin to experiment with the DECT NR+ v1.1.1.0 FW.  Initially, I'm noticing on obvious difference in the behavior of the dect_hello sample between v1.0.2 of the FW and v1.1.0.  With v1.0.2, the "hello" messages are sent at 5 sec intervals, as configured in the RX_PERIOD_S var in the Kconfig file.  However, when the same dect_hello sample is run using v1.1.0 of the FW, it seems to almost not wait at all (less than 1 ms) between transmissions.  It seems to wait very little time to try to receive a packet before moving on the next transmission.

My output from v1.1.0 + hello_dect is the following:

To observe this issue, pls do the following:

1. Load v1.0.2 of FW

2. Load dect_hello

3. Execute and observe the interdeparture time of 5 sec.

4.   Load v1.1.0 of FW

5.. Load dect_hello

6. Execute and observe the interdeparture time of less than 1  ms.

Pls let me know if there is anything I can do that can fix this.

Thanks!

Best,

Steven Gordon

    Hello Steven, 

    I've been asked to follow up with the issue you are describing. 

    I can see the same result on my side. I programmed the hello_dect sample from NCS v2.9.1 and see the same issue with dect modem fw.

    Hi Steven, our DECT team informed me that there has been some API changes and thus you must use nRF Connect SDK v3.0.0 with mfw-nr+_nrf91x1_1.1.0-47.alpha. 

    Can you please test and let me know how that works?

    Kind regards;
    Øyvind

    Øyvind,

    I tried it and it does work.  Thanks for the insight.

    However, in the process of trying this, I discovered something I don't understand.  After upgrading to sdk 3.0.0 and toolchain 3.0.0, I used the existing dect_hello project (which was created with sdk 2.9.1) and created a new build configuration where I specified sdk 3.0.0 and toolchain 3.0.0.  This build consistently failed, ever after reinstalling all fo the components of the NRF Connect environment.  

    However, when I recopied the hello_dect sample using sdk 3.0.0 (rather than using the project created under sdk 2.9.1 with a new 3.0.0 build config), it did build and flash properly.  Can you tell me why this is?

    Thank you.

    Best,

    Steven Gordon

    Hello, 

    Unfortunately there are no release notes of these changes. Our DECT NR+ developers state that the main difference is that the separate callback_apis have been replaced by a single event-based callback. Additionally, the startup process has changed due to the new operation mode configuration.

    Here is a quick diff between nrfxlib/nrf_modem/include/nrf_modem_dect_phy.h in both v2.9.1 and v3.0.0

    Does anybody know if that events callback is called inside ISR context or inside zephyr thread context? 
    Are there any strict limitations for the time processing inside that event callback handler?
