Re: Arduino interface definition for Nordic development kits

Erwan Gouriou
 

Hi Aaron,


My question is that, do I need to add Arduino interface definition to each of the Nordic development kit's DTS files?

This is indeed the expected way to do it.
Don't forget to also add "arduino_i2c" in boards' yaml files.

Cheers
Erwan

Arduino interface definition for Nordic development kits

Aaron Xu
 

Hi,

When I try to compile "samples\shields\x_nucleo_iks01a1\" for my Nordic dev. kits(pca10040 and pca10056), occurred this error:

Error: nrf52840_pca10056.dts.pre.tmp:437.1-13 Label or path arduino_i2c not found
FATAL ERROR: Syntax error parsing input tree
...
Call Stack (most recent call first):
...
-- Configuring incomplete, errors occurred!

I noticed that the Arduino interface, like default i2c and so on, not been included in the Nordic dev. kits, either pca10040 or pca10056. So I add this patch to nrf52_pca10040.dts under "zephyr\boards\arm\nrf52_pca10040":

@@ -97,7 +97,7 @@
        cts-pin = <7>;
 };
-&i2c0 {
+arduino_i2c: &i2c0 {
        status = "ok";
        sda-pin = <26>;
        scl-pin = <27>;
 
And it works.

My question is that, do I need to add Arduino interface definition to each of the Nordic development kit's DTS files?

Re: Long-Term Bluetooth Mesh Reliability

Martin <ma@...>
 

Hi Johan,
thanks - that's good to know for sure. No luck unfortunately, my
device is still not responding after some time. I have set
CONFIG_DEBUG=y and from my understanding the application seems to run
into an usage fault, which is not printed on UART unfortunately. If
you are interested, I have attached myself to bug #12726 which seems
to be about the same thing.

Best,
Martin

Hi Martin,

I am wondering if someone has already made experiments regarding the
long-term reliability of Bluetooth Mesh in Zephyr OS?

The reason why I am asking is this: I am on the latest master and I
use a Mesh setup consisting of ~10 devices (PCA10040 + PCA10059) with
an adjusted samples/boards/nrf52/mesh which additionally sends
heartbeat messages and at the same time blinks an LED (realized by a
timer that submits a work item which lights it, waits and switches it
off again). What I have been observing is the following: Devices that
only send a hertbeat message every 10 seconds run quite stable for
some days, but need to be power-cycled at some point in time (no
heartbeat messages, no LED blinking). Devices with higher load (e.g.
relay enabled, deliberately sending a higher amount of mesh messages)
are not responding within hours (no messages whatsoever, no LED
blinking). Even when taking pressure out of the mesh (not deliberately
sending messages anymore), they do not come back to life before I
power-cycle them.

Does someone possibly have an explanation for the issues I am
encountering or some tips regarding what I can try to tweak? I am
still trying to debug this issue but right now my results are not
meaningful expect that no new output appears in the serial console as
soon as the devices stop responding. On an older revision, I
presumably was hit by #12726 (paused execution and saw that next
pointer of queue was pointing to the current element), but could not
reproduce that I am still hit by it with the latest master.
I’m not aware of any such issues (long term usage instability), at least not in the Bluetooth/Mesh code itself, however you might want to retest together with #13431 which was merged yesterday, in case the cause of your issues is a stack overflow.

Re: Get RSSI in DTM(Zephyr)

Ryan Erickson
 

Hello Tommy,

 

You can look at the Bluetooth specification to learn more about DTM mode.  I do not have any code or documents to share.   You will have to dig into the zephyr source code to see how you can implement your own DTM command to give you RSSI.

Hi Isaac,

Generally you would be measuring the RSSI on the test equipment from a signal generated by your Bluetooth radio, and would be using a calibrated accurate test system. The nRF51824 (from the product spec) has an RSSI accuracy of +/-6dB, that is wildly inaccurate and I cannot see any reason to want to measure/record it on every module. You can add a non-standard command to read and return the RSSI if needed to the DTM code.

Thanks,

Jamie

Hi Vinayak,

 

Our customer requested us to test conductive BLE RSSI in factory for accuracy improvement.

Could you please clarify the following questions?

  1. As I know, BLE RSSI can’t be measured in standard DTM mode. Is it possible to add new feature in DTM to support BLE RSSI measurement?
  2. If the answer to the above question is “no”, I still need your confirmation if other test modes exist that can measure RSSI except DTM mode.

In our experiences of other algorithm(LTE/WCDMA…etc.), RSSI usually can be detected easily in test mode via a CW tone. So it’s why we want

to double check this.

  1. Do you have any customers who have experiences to measure conductive RSSI in factory or in lab? If so, can you share the methodology?

Any other changes we need?
Great! That should be enough.

I had a couple of issues with openocd on an RV32M1 earlier on.
The issue was related to selecting the boot mode and then flashing an application, , but I cannot reproduce it now with -rc2.

Thanks,
Brix

Hi Anas,

Sweet! I have been using -rc2 for my daily work for the last couple of weeks without issues.

Well, except one. Is it possible to pull in the RISC-V RV32M1 support patches to openocd in the final 0.10.0?
Currently, we need to use a custom openocd when dealing with this SoC (see e.g. https://docs.zephyrproject.org/latest/boards/riscv32/rv32m1_vega/doc/index.html).

Hi,
We are excited to announce the availability of a new pre-release of the Zephyr SDK.

This release of the SDK provides a major update to all tools and toolchains. The current SDK was based on yocto, this release uses crosstool-ng for the toolchains and yocto for the host tools.

Major changes in this release:

· Use crosstool-ng for building the toolchains
· Update toolchains to GCC 8.2
· bossa: Update to 1.9.1
· qemu: Update to release 3.1.0
· Update openocd to Zephyr Branch from 20190130

The SDK is available for download from https://github.com/zephyrproject-rtos/sdk-ng/releases/tag/v0.10.0-rc2


Knowns issues:
- Newlib with xtensa targets does not work yet.
- 1 nios2 tests fails to build


If you find any issues or have general feedback, use the following issue system to report:

Re: Get RSSI in DTM(Zephyr)

Hi Ryan,

Thanks for your response.

 

Could you share if there are any reference code for DTM RSSI.

 

Thank You,

Hello Tommy,

 

Per the Bluetooth Spec, there are no DTM commands to obtain RSSI.  You would need to add your own custom command in firmware.

Hi Jamie,

Sorry to bother you.

I use hci command LE Receiver Test Command and LE Test End Command let DUT enter Test mode and can get packets from equipment successfully.

Equipment send 1500 Bytes with RSSI(70 dbm) to DUT

 

At the same time , I try to launch “btmon” tool to get RSSI information , but I can’t get any RSSI.

 

 

Are there any methods can get RSSI in DTM?

 

Thanks

Tommy

Hi Isaac,

Generally you would be measuring the RSSI on the test equipment from a signal generated by your Bluetooth radio, and would be using a calibrated accurate test system. The nRF51824 (from the product spec) has an RSSI accuracy of +/-6dB, that is wildly inaccurate and I cannot see any reason to want to measure/record it on every module. You can add a non-standard command to read and return the RSSI if needed to the DTM code.

Thanks,

Jamie

Hi Vinayak,

 

Our customer requested us to test conductive BLE RSSI in factory for accuracy improvement.

Could you please clarify the following questions?

1.     As I know, BLE RSSI can’t be measured in standard DTM mode. Is it possible to add new feature in DTM to support BLE RSSI measurement?

2.     If the answer to the above question is “no”, I still need your confirmation if other test modes exist that can measure RSSI except DTM mode.

In our experiences of other algorithm(LTE/WCDMA…etc.), RSSI usually can be detected easily in test mode via a CW tone. So it’s why we want

to double check this.

3.     Do you have any customers who have experiences to measure conductive RSSI in factory or in lab? If so, can you share the methodology?

 

 

Best Regards

Hi ,

We have a product using nRF51824 with zephyr.

We use hci_uart sample code and follow below link , and we can get other BT device’s RSSI.

https://devzone.nordicsemi.com/b/blog/posts/nrf5x-support-within-the-zephyr-project-rtos

 

We have a question , If it is in DTM(Direct Test Mode) , how can we get RSSI?

Could you give us some suggestions.
