Hi all, I tried to steal some code from the Twizy module but obviously don't understand how it works... my code results in a boot loop. I would like to have a possibility to test OBD codes in the shell (something I think would be immensely useful as a general function; that way, getting started with a new vehicle would be much easier.) Anyway, the problem seems to be in the lookup of the command name I'm trying to register, see stack trace below. Any help is greatly appreciated! Thanks, sharkcow 0x400fc115 is in std::_Rb_tree<char const*, std::pair<char const* const, OvmsCommand*>, std::_Select1st<std::pair<char const* const, OvmsCommand*> >, CompareCharPtr, std::allocator<std::pair<char const* const, OvmsCommand*> > >::find(char const* const&) (/opt/esp/xtensa-esp32-elf/xtensa-esp32-elf/include/c++/5.2.0/bits/stl_tree.h:663). 658 (this->_M_impl._M_header._M_parent);
