Timeouts on Macos proxmark3 client

Using the PM3 on a Mac, I recently noticed that whenever I compile the proxmark3 client with gui support, communications seem to become a lot less reliable: lots of timeouts waiting for the proxmark to answer, some commands failing, etc.

If compiling the proxmark3 client without gui support, everything works great. If there are other Mac users out there, could you run that test (run with code compiled for gui support, then run with code compiled withtout gui support) and report on this thread?

The clearest symptom: start the client, do a "hf search" with a HF card on the reader. It should work fine. Then wait 30 seconds to 1 minute doing nothing: on the gui build, any new commands will either fail with a timeout, or work only occasionally. On a text-only build, everything will continue working as normal.

Looking forward to your feedback

Re: Timeouts on Macos proxmark3 client

that sounds like the slowdown feature "app nap" built in functionality..

disableAppNap("Proxmark3 polling UART");

Re: Timeouts on Macos proxmark3 client

To the best of my knowledge this was fixed about a year ago in v3.1.0 official repo:
https://github.com/Proxmark/proxmark3/releases/tag/v3.1.0

@chocol4te what version fork are you using?

Just pulled from github.com:RfidResearchGroup/proxmark3.git, commit 7870dd6fc00e20c9d11ee070fda52414a5709693, built and flashed, and now I can't replicate it hmm

Re: Timeouts on Macos proxmark3 client

Could you please apply https://pastebin.com/gz74QduB:

curl https://pastebin.com/raw/gz74QduB|git am -

and report back the debug output you get next time the issue occurs?

If possible please check the AppNap status in the activity monitor during timeouts. AppNap should never be Yes.

Re: Timeouts on Macos proxmark3 client

@AntiCat

I am currently on the Catalina Beta, which has an Activity Monitor bug preventing me from seeing any process information (https://i.imgur.com/SFp1H97.png).

I've applied the patch, I'll send the output next time it happens

Aren’t the columns simply to wide? Please try to resize the window.
Note: The status is only relevant during the error.

if I'll try to send command to the device

[usb] pm3 --> hw status
UART:: write time-out
[!] Status command failed. Communication speed test timed out          
[usb] pm3 -->

kernel_task still heavy load cpu
only one way - disconnect and connect usb cable

this case kernel_task load drops near the zero

after that device works again
