2021 Overview notes to review
On this page indentation of URLs highlights when one post refers or links to another.
Worth noting, Nordic Semi web site is organized into three domains:
primary Nordic Semi website :: Nordic Devzone :: Nordic Semi Documentation
Searching for articles, tutorials and other materials in one domain does not in general appear to find or capture search results in the other two Nordic Semi site domains. An on-line power profiling tool can be found indirectly at Nordic Devzone by entering search pattern "online power profiler". The link to the profiler for nRF91xx family parts is:
- https://devzone.nordicsemi.com/power/w/opp/3/online-power-profiler-for-lte Nordic Semi Online Power Profiler for nRF9160
Some related links to Nordic on-line power profiler:
- https://devzone.nordicsemi.com/power/w/opp Nordic power profilers for nRF91xx and nRF52 and 53 family SoCs and SiPs
- https://devzone.nordicsemi.com/power/w/opp/4/user-guide-lte Online power profiler user guide
A local wiki page is in progress as well relating to LTE modem commands, both universal ones and some of Nordic Semi's custom AT commands:
A helpful summary of all firmware development tools offered by Nordic Semi:

At Nordic Devzone issuing search string "nRF9160 configure PSM and eDRX" . . .
Developers Shital, Hoang, Erik posting about modem PSM and eDRX modes, mention of asset_tracker nRF9160 sample app:
Need to asure Secure Partition Manager not using UART for any logging or other purpose:
AT modem commands to set power saving mode parameters and eDRX params:
Cerca 2019 Q2, as of ncs v1.3.1 the enabling of PSM and eDRX does not leave a way for application firmware to be notified when modem wakes from power savings mode:
Cerca 2021 Q2, GPS use where PSM and eDRX are not available. Plus AT commands to return whether eDRX can be used, whether PSM can be used:
Mention in third or fourth reply about SIM card minimum interval needed to deactivate, with respect to eDRX setting:
To set the CONFIG_MQTT_KEEPALIVE equal to your polling interval . . .
nRF9160 maximum device sleep period and maximum device reachable period:
Only necessary to set PSM and eDRX values once, LTE modem retains them, honors what values it can given mobile network provider:

^ Toolchain Related
^ To Set cmake Options In SES
As of 2021-09-24, using Segger version xxx Nordic's version, this Segger IDE offers an extra menu item to open, build, flash and debug nRF SDK sample apps. The initial dialog box which appears for this option is titled "nRF Connect Options". Just left of the title there is a Nordic colored icon showing two links of chain, white on blue.
There are five input boxes, a mix of text inputs and drop down menus, and two sets of radio buttons. The free form text input box titled "Extra CMake Build Options" is a key place to express custom configuration settings to `cmake`. To use, for example, Zephyr's latest stable arm cross compiling toolchain in place of Nordic's close but not quite as recent chosen release of GNU ARM cross compiler toolchain, the following `cmake` option needs be entered here:
-DZEPHYR_TOOLCHAIN_VARIANT=zephyr
The default value for 'ZEPHYR_TOOLCHAIN_VARIANT' with Nordic's SDK v1.6.1 is 'gnuarmemb'. It is not sufficient to set a variable by this name in the shell environment of Linux systems, nor is it sufficient to set a Segger global or project macro by this name equal to the string "zephyr". This change in toolchain name or branding must be passed to `cmake` on its command line. In Segger, we build with a button press, so the command line option is only accessible to us from certain limited place or places. This text input box is our place to express needed custom command line options to `cmake` when working within SES.

As a note here which will also be mentioned near the beginning of this NN wiki page, it is as of 2022-05-09 Monday possible to access any Nordic Devzone post by its number, by entering a URL of the form https://devzone.nordicsemi.com/f/nordic-q-a/nnnnn/index.asp. This works for posts all the way down to Nordic Devzone's first post, post number 1, which was posted cerca 2013.
The following posts cover interesting and in many cases likely useful topics relating to low power, edge sensing devices. These posts however are not yet sorted by NN wiki users. They are here for further review, possibly on a rainy day, but in either case to fulfill future technical needs:

Hello CircuitDojo Community,
In a [recent post](https://community.jaredwolff.com/d/222-nrf9160-sleep-and-low-power-control-areas/2) I inquired about low power configurations for the nRF9160 and boards based on this SiP. Jared Wolff shared code which dynamically turns off a given UART of the SiP's application processor. In his code there's a call to a routine named `uart_rx_disable().` I'd initially overlooked this. Today as I try to build my application I'm blocked on a link time error "undefined reference to `'".
Per Jared's code excerpt I have added `CONFIG_PM_DEVICE=y` to my prj.conf. My project is based on Nordic's aws_iot sample app. I am using the ncs SDK version 1.6.1. Nordic's fork of Zephyr in this SDK is Zephyr release 2.6.0.
Where should `uart_rx_disable()` be defined? Am I using a too old version of ncs or Zephyr RTOS?
