How to turn off and on BLE functionality wirelessly using nRF UART/some other application without touching my deployed application?

Hello, I want to hide the BLE(RF signals) completely soon after updating the configuration in my application and whenever I need to update the config I should be able to enable it and update the config wirelessly without touching the deployed application. Is it possible to turn off and on BLE functionality wirelessly using nRF UART/some other application? If yes, can you share the reference on HOW part? TIA. Regards, Arya

nRF9160 date-time example

Hey, I have isnstalled ncs v1.3.1 and the toolchain specified in the instructions ofr 1.3.1. I am trying to utlise the date-time library in the https_client example. I ahve included the header in the main and after the network connection is established I call: s64_t date_time_stamp; k_sleep(K_MSEC(25000)); //Wait some time to make sure the Date-Time update has happened date_time_now(&date_time_stamp); printk("Date time: %016llX\n", date_time_stamp); In the prj.conf file I have added: CONFIG_DATE_TIME=y CONFIG_DATE_TIME_UPDATE_INTERVAL_SECONDS=10 When I try to build I am getting: [0/147] Performing build step for 'spm_subimage' ninja: no work to do.

Missing documentation on TinyCbor for nrfConnect SDK 1.3.0

Hi, I am trying to use Cbor library provided the SDK version 1.3.0, I have added the module in my prj.conf file, however the documentation (at the top of cborencoder.c) that describes the cbor_encoder_init function has different parameters on its usage of what the source code has. From the source code we have: void cbor_encoder_init(CborEncoder *encoder, cbor_encoder_writer *writer, int flags) { encoder->writer = writer; encoder->added = 0; encoder->flags = flags; } But the documentation at the top of cborencoder.c has the following for when ilustrating its usage: cbor_encoder_init(&encoder, &buf, sizeof(buf), 0); Does anyone knows how this is supposed to be used?, is there any documentation anywhere on how this is used? Any help would be appreciated.

nRF Sniffer shows advertising interval too small

Hi, According to below thread, the advertising interval has a random 0 - 10 msec delta, so if the adv interval is 20 mses, if run it for long enough, will the result be close to 20 msec? or will be anywhere between 10 - 30 msec? https://devzone.nordicsemi.com/f/nordic-q-a/46115/advertising-interval-time-test I capture data using 1 nRF52840 DK and 2 nRF52840 dongles. For the first 1000 adv, it took 818 msec in total, does it mean the adv interval is 0.818 msec? In this case, it does consume a lot of enery. For the first 2000 adv, it took 13.709 sec, so the interval is 6.855 msec? See screen shot below.

nRF9160 custom board overlay for am335x (linux)

We are using a nRF9160 and are interfaced to a Texas Instruments AM335x running Linux over a UART interface. I've read through the guide on making a custom overlay. So far, I have copied the nRF9160dk_nrf9160, and have renamed references for our board. The dk board interfaces to an MCU. Looking at the various files, there are components such as buttons and leds that are unique to that board that don't exist on our board. On our board, we use p0.00-p0.03 as gpio. Outside of UART, the only other pin into the nRF9160 is the power enable. The one thing I've noticed in the dk overlay is reference to NRF52840_GPIO_RESET_PIN which is something unique to the dk. What pin on the nRF9160 is this going to? If we need this reset, it could be done using p0.00-p0.03? The am335x is not in the list of supported mcu's. The closest thing

Error when opening an nRF Connect SDK project - Linux Ubuntu 20.04

This is the third time attempting to install nRF Connect SDK on my Linux box at home, and have failed at the same place every time. I followed all the instructions while using the Getting Started Assistant, and verified that all the steps were done correctly. When I go to open a connect sdk project, select the application/sample I want to run, I get this error: This is what my nRF connect options look like when going to tools -> options -> nrf Connect I have successfully installed this on my windows PC that I use at work, and vaguely remember there needed to be some cmake options selected or something. I could really use some assistance as we are purchasing many nrf9160's to use in our fleet management product. Thank you! -Kyle Garland

Question about set section placement macros on embedded studio

Hi, I am trying to set the section placement macros on the segger embedded studio. Follow some instruction, find "project -> Option -> Linker" I cannot find the set about "section placement macros". The only thing looks similar is "Memory map macros". But it doesn't work. The project I load is "blinky_pca10056". And I am going to set the section which corresponding to the nRF52840 Dongle. Would it because of the segger embedded studio, or I load the wrong Keil MDK project? Thanks a lot for any advice, Leo

Is there any valid tutorial using Eclipse IDE for development on nRF52 devices?

I have found a few "how to" on cofiguring Eclipse for application development on nRF52 devices. After some point things are not as described in this guides. So, Is there any solid and updated tutorial on how to use Eclipse? Something that actually works and preferbly on windows. Currently I am using SES but it is so primitive compared to other IDEs (for example microsoft visual studio or atmel studio or even MPLab-X) that make my everyday life hard. For instance, indexer is so slow that it is faster to find the definition of a function by myself than waiting the atl+G key combination to take me there. Imagine using an SDK (like the one Nordic offers) with tens of files and dependencies between them, to have to remember or even more search for a particular variable or function. Can anyone be productive working like this? I don't want to

Zigbee + FreeRTOS End Device power consumption

Hi, We have been working with an end device based on nRF52840 with nRF5_SDK_for_Thread_and_Zigbee_v4.0.0_dc7186b By measuring with the power profiler kit, we got a system's power consumption of about 50uA. But after we call zboss_start_no_autostart() and zboss_main_loop_iteration() periodically (we tried from 50ms to 1s) we realized that the current consumption varies from 500uA to 1mA. This is how the Zed is configured: zb_set_ed_timeout(ED_AGING_TIMEOUT_64MIN); zb_set_keepalive_timeout(ZB_MILLISECONDS_TO_BEACON_INTERVAL(3000)); zb_set_rx_on_when_idle(ZB_FALSE); Since we're using FreeRTOS and SoftDeivce, we can't call zb_sleep_now(). Is there any way to turn off radio during inactivity times or any other considerations? Also, is there any improvements on this topic between nRF5_SDK_for_Thread_and_Zigbee_v4.0.0 andnRF5_SDK_for_Thread_and_Zigbee_v4.1.0? Thanks in advance. Regards, Santiago

Change advertising data every interval with scanning

I can listen for radio inactive event according to this post https://devzone.nordicsemi.com/f/nordic-q-a/9137/change-advertising-every-time-event but I am scanning at the same time with scan window > 2 * advertising interval. Is it possible for 2 advertising intervals to occur without getting a radio inactive event in between because the scan window occurs in between? For example, I use scan interval=10s, scan window=100ms, advertising interval=40ms. I don't want to set a periodic app timer to wake up just to change the advertising data. I want to change the data while already awake to save power.
