nRF52840 Sense Power Verification Problem / Bluefruit Library

Products & Technology XIAO
#1

I have run through the Getting Started page on the wiki up to the Power Consumption Verification portion. I am able to run the blink sketch, but when I try to run the demo_sleep sketch I get errors. I am using the factory boot loader and have installed tried both the vanilla SDFat and Adafruit branch of SDFat.

Snippet from deep_sleep.ino:

What is the Bluefruit library? Is it supposed to be available in the Arduino IDE by default or do I have to install it?

#2

To use “bluefruit.h”, the BordServicePackages must be “Seeed nRF52 Borads”.

#3

Like this, I assume:

Seeed nRF52 Boards

That does change the result, but not much.

What you need is not BoardSelect but BordServicePackages.
For ArduinoIDE, follow the steps below to install BSP.
Tools–>Board–>Boards Manager–>Seeed nRF52 Boards

#5

I had already done that.

BoardServicePackage-nRF52

Is there something I need to do to apply that package to my board or project, perhaps?

#6

“C:\Users\xxxxxx\AppData\Local\Arduino15\packages\Seeeduino\hardware\nrf52\1.1.8\libraries\Bluefruit52Lib\src\bruefruit.h” is installed?

If you show me your entire sketch, I can try to compile it. Could you post it with an attachment file or </>?

#7

It is.

(base) ➜  src pwd
.../Library/Arduino15/packages/Seeeduino/hardware/nrf52/1.1.8/libraries/Bluefruit52Lib/src
(base) ➜  src ls bluefruit.h
bluefruit.h

I’m running the unaltered demo deep_sleep.ino from the BlueFruit examples repo.

#8

The BSP provided by Seeed does not include the DeepPowerDowe() function, which causes a compile error. flashTransport.runCommand(0xB9) can be used instead of DeepPowerDowe() to compile. See the sketch below.
sketch_apr15a.zip (1.9 KB)

You may be able to avoid the compile error by replacing the BSP with one downloaded from Github (I have not tried).

The following links may be helpful to you. Please try the attached sketch in post 1/3.
