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 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 @@ 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

Hi Johan,
toggle quoted messageShow quoted text
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 Am So., 17. Feb. 2019 um 15:59 Uhr schrieb Hedberg, Johan <johan.hedberg@intel.com>:

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.

Thanks Tommy From: Jamie Mccrae [mailto:Jamie.Mccrae@...]
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?
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.

Hello,
I am using the NRF52840, UART1 with hardware flow control turned on. I want to be able to detect transitions on the CTS pin (input). Currently I tried using the GPIO driver to configure interrupts on both edges and this seems to work great for monitoring the CTS pin state. Is it alright to use the GPIO driver to do this when the UART peripheral is using that IO as well? I am looking for confirmation that this should work and not cause me any issues. Thanks, Ryan

Long-Term Bluetooth Mesh Reliability
Martin <ma@...>
Hi,
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. Thanks, Martin

Re: West Issue

Hi,

Why are you using sudo to run ninja flash? That will execute ninja as root and therefore also west as root. When you are running “west init” you run it as your regular user. Regards, Brix -- Henrik Brix Andersen
