No problem, I was sort of working through similar questions so I thought I would just throw out what I was looking at. If it helps...great, if not...well... the answer is out there...somewhere.

Hi, again AMarch01.

Sorry for the lack of answers. Call it Christmas ..., but anyway, I beg your pardon.

I am afraid we still haven't gotten the right answer, but your comments are slowly helping me reach the goal. I have to investigate a bit, but if I find some relevant info, be sure I`ll let you know. Thanks

Found this one, which seems to indicate that changing the inteval (for advertising) may be difficult

Probably more detail then you want at the moment, but I am examining parts of the BT Controller to figure out how the low-end pieces function, or where they exist at least.

LE Controller — Zephyr Project Documentation
and pieces found here

ncs\v2.x.0\zephyr\subsys\bluetooth\controller\ll_sw

Maybe this information doesn't help you ...

I think what is funny about your question, is that I plan on opening that project in the near future here and attempt to adjust the very same variables you mentioned among others. I am guessing that they are a part of the prj.conf variables. There is a common variable list in Zephyr / Nordic that adjust the parameters, and then you specify them in the proj.conf file.

Right now the file proj.conf ontains the following:

CONFIG_BT=y

CONFIG_LOG=y

CONFIG_BT_DEVICE_NAME="Test beacon"

I would start searching around for the CONFIG_BT switch to find other switches to help with configuration. They are in there somewhere.

There are probably some library calls that can do the modifications dynamically, but I haven't searched for them yet.

The sad part is that I don't have an answer for you.

Hi SwRa.

Thanks to AMarch01 and you, I've found the Beacon application I was looking for in the actual nRF Connect SDK. Therefore, I won't need to port the old example from the nRF5 SDK to build it up and determine the minimum memory I need to run this app in a Nordic SoC.

However, checking the main.c file on this app, I don't find elements (API functions?) to change several properties of the SoC that are critical in my project (like the device name, the output power, the advertising PHY modulation, the interval, the duration, or the adv_data_flags), elements, all of them, being accessible in some of the examples I tried in the past (for instance in one called ble_app_uart) using in this case, the old nRF5 SDK, allowing me to change all the mentioned parameters and fine-tune the module based in a nRF52840 SoC.

Would you please let me know where to find these functions to perform the same fine-tunes I made on the nRF52840 and see how the fact of having an SoC with much less memory and no receiving radio affects the chip autonomy on the Beacon.

Thanks

Juan

I would imagine that such a task would be difficult, the nrfx library probably doesn't mesh together the same way and unraveling any pieces that are under cmake control would be an effort.

Beacon appears to be a generic operation for BLE so a generic example would be found in
v2.7.0\zephyr\samples\bluetooth\beacon\

I attempted to build this and when the zephyr build is completed using NCS under VS code I get an ending output report as follows:
[186/186] Linking C executable zephyr\zephyr.elf
Memory region Used Size Region Size %age Used
FLASH: 99692 B 1 MB 9.51%
RAM: 26632 B 256 KB 10.16%
IDT_LIST: 0 GB 32 KB 0.00%

This was to a nrf52840-DK target.

It is a good idea to follow the Nordic education guides with the latest software products. There are guides on how to configure and use the nrf Connect SDK using VS Code.

Hi AMarch01. Thanks for your time.

In my case, I want to know the memory layout and size I need to choose the most convenient Nordic SoC and implement a transmitting-only beacon using the new toolchain and VSC IDE Nordic is now recommending.
In the old SDK and for a Segger IDE environment, an example called ble_app_beacon was described. Still, unfortunately, the new nRF Connect SDK (v2.7.0 in my case) did not include this example. I could use the actual Segger IDE environment, but since the old nRF5 SDK hasn´t been maintained for some time, I suspect the setup will give errors.
So my question is: Could I Build-Flash this old Segger .emProject file into my nRF52849 DK using the VSC IDE, toolchain, and nRF Connect SDK that Nordic recommends nowadays (i.e., the one described in the nRF Connect SDK Fundamentals DevAcademy course) and see the memory details I mentioned?

Waiting for your comments,

Regards,

Juan

Hi Juan,

We have two SDK's, The nRF Connect SDK and the nRF 5 SDK (Older SDK).. All the documentation for each of the SDK's can be found in the Technical Documentation Website here: https://docs.nordicsemi.com/

The Sample that come under the SDK's can be found here:

nRF Connect SDK: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples.html

nRF 5 SDK: https://docs.nordicsemi.com/bundle/sdk_nrf5_v17.1.0/page/examples.html

Additionally, we also have tutorials on BLE, WiFi and Cellular fundamentals as well as working with nRF Connect SDK in the DevAcademy page that you could refer: https://academy.nordicsemi.com/

Best Regards,

Swathy

Using the new SDK , you can find them under \ncs\v2.7.0\nrf\samples. Download the latest nrfconnect for desktop, click on the Toolchain Manager and download the latest (2.7.0 in my case).
Wait a long while it downloads the whole world (code and tools) and you will find many of them in the relative directory I just specified.

The old SDK still exists, but it isn't going to be supported. You can find it someplace on the website.

How about a link
nRF Connect for Desktop - Downloads - nordicsemi.com

Link to the old SDK
nRF5 SDK downloads - nordicsemi.com
