How to find currently installed nrf51 software version?

[max]

Hi,

when connecting the crazyflie to the cfclient the console shows:

Code: Select all

SYS: Crazyflie 2.1 is up and running!
SYS: Build 27:2c99828abed6 (2021.06 +27) CLEAN
[...]

I assume that (2021.06 +27) means the STM32 software version.
Can I somehow see what software version is running on the nRF51?

I haven't flashed the nRF51 since I got the crazyflie. Hence, I assume that it is running 2020.06 or an earlier version.
That assumption is built on the assumption that the date on the sticker on the box is the date of manufacturing or packaging. It says 08/28/20.

Best regards,
Max

an easy way is to just flash the version you perfer

I agree, that helps if you start doing things and think about that question.
Unfortunately it does not help if you want to change the nrf firmware and would like to know what the state is you're leaving.

The whole reason I want that information is to document that everything I did so far happened with the firmware version X, I've been running so far and everything else will happen with firmware version Y that I know of since I flashed it myself.

Hi!

I agree this sounds useful, I filed an issue here: https://github.com/bitcraze/crazyflie2- ... /issues/58

Thanks!

Hi Jonas,

thanks for opening the issue.
But that means that there is no way to get the installed version at the moment, right?

Btw: I figgured that my nrf version is most likely before 2020.06 as the M2 led starts flickering at around 30 °C surface temperature of the nrf (measured with thermometer) and turns off at around 33 °C.
From this thread I take that the nrf measures around 15 °C more and thus reaches the max temperature of 45°C.
That temperature was changed to 60 °C in 2020.06

You most likely have the 2020.02 nrf release.

That's good to know!
How can you tell?

I double checked and it is most likely the 2020.04 nrf release. This was the FW used in production at that period of time when your unit was manufactured, if you haven't updated it.

Cool, thanks for the insight!
