scan Aborted

[jeremyarnoux]

Hi,
I'm working on a plugin for Jeedom in partnership with Switchbot who generously sent me all of their hardware for testing.
So I would like to complete the list of devices :-)

Je rencontre un petit problème lorsque je lance le scan, j'ai l'erreur suivante :
terminate called after throwing an instance of 'std::logic_error'
what(): basic_string::_M_construct null not valid
Aborted

Do you have any idea where the problem comes from?
Thanks for your help !!!

The last device is a SwitchBot LED Strip Light, correct?

Which is not supported by Decoder (yet), so no decoding expected, but it also shouldn't throw an exception and terminate the scan.

Investigating about the exception …

@jeremyarnoux, could you try this branch in which i have included a change which should fix your issue for the time being

https://github.com/DigiH/decoder/tree/TPMS-test

[DigiH]

@jeremyarnoux - has your issue been fixed with the above change in the latest dev branch?

Hello,
I'm got this error when using ScanAndDecode.py (use actual code from develompent branch):

Thanks for the report. I'll have to have a closer look at this.

@alrzbv @jeremyarnoux the Python example you both have likely been using is missing sending the MAC address to Decoder, which is necessary for some decoders to work.

We'll need to amend the example, please hold on for a bit …

[DigiH]

@alrzbv @jeremyarnoux, can you amend your code with the additions in

b53ab08

and give feedback if this issues is resolved with it?

[alrzbv]

no more errors, for me. thx!

[DigiH]

Closing, as the example additions have been integrated into the 1.2.0 release.
