What I'm looking to do is actually to be able to automate measurements.
I e be able to read data from the unit and possibly "press some buttons" from say a python program.
Maybe something like this can be done via bluetooth?

Depending on the precision you are looking for, you may be able to accomplish what you want with one of these hooked up to an Arduino with an SD card.

I've used the INA219 to log voltage, current, and burden voltage, worked great. Very easy to set up if you've done Arduino stuff before.

Hacking (or modifying) the software can interfere with reliability as well.  I think the real point here is that you need to acquire something other than a hand held DVM.

Or:

Since there is a way to transfer data over bluetooth, maybe  I have no real.need for hacking either sw or hw...

The current FW is still 1.58 beta, and has been for a long time.

To this moment, it seems to be stable and probably the best one delivered.
It does indeed look less beta than other versions.

Is there any plan to make it "gold"?
Is a new FW in the working?

I just bought the 121GW from Welectron here in Europe and it came with firmware 1.61 so the 1.58 is already "old"

Also, as has been mentioned before, the manual only has changelog information up to 1.51. Would it perhaps be possible to give us an update on the firmware status?

I do like my meter, but I'm very much looking forward to stable firmware with changelog information.

Oh, nice, let's hope the firmware shows up on the EEVblog site soon.

On the SD card you should finde a file called EEVBlog.bin that you may upload here for us. This is the firmware file.

Interesting!
This firmware revision 1.61 is not available on Dave's website with the other firmware versions, latest on his site being 1.58.
I cannot find anything on the Github under EEVBlog.
Please attach a copy of firmware V1.61 if possible for the rest of us to try out.
Whats happened to the firmware list on EEVBlog website for the 121GW being updated as new revisions become available ?

Just checked the sd card and it is empty. Did they leave a copy of the firmware on the sd card earlier ?

@Dave what is the status on new firmwares? Why aren't the latest posted on the website (and the changelogs)?

Still no response here and no update on the official firmware support page. Hope that product support is not already suspended  :--

Guys, this thread is not about stock firmware, nor about support. This thread is about developing a new firmware. So, Dave is not supposed to answer. Sorry for misleading title (it started as reverse-engineering of stock firmware). Please ask in https://www.eevblog.com/forum/testgear/eevblog-121gw-discussion-thread/ or https://www.eevblog.com/forum/testgear/eevblog-121gw-multimeter-issues/
