Pablo,<br class="">
<br class="">
a bit more information on how you connect to the car would be
helpful here.<br class="">
<br class="">
Arbitrary remote shell command execution is supported by the
module's HTTP API (/api/execute), the module's SSH server, the "V2
protocol" server via MP command 7 and any "V3" (MQTT) server via the
/client/command topic scheme. Plus there's a secondary
(non-standard) HTTP command API available on my server
<a href="http://ovms.dexters-web.de/" target="_blank" class="">ovms.dexters-web.de</a> (public API of my custom web shell).<br class="">
<br class="">
Lock & unlock are also available as fixed MP commands (20,22) on
a V2 server, along with a set of other standard App calls. These do
not run via the shell but translate to direct internal execution.<br class="">
<br class="">
Command execution has not yet been implemented for the "V2" server's
HTTP API. But you can of course implement that if you use that API.<br class="">

<div dir="ltr" class="">Hello OVMS team, we are currently working with an
implementation with OVMS in a react native app with a NodeJS
back-end.<br class="">
Currently we can connect with the cars and rescue some data like
the status of the battery or GPS location, but now we need to
send commands to lock and unlock the cars from the same app,
when we send a command I get a response that the command is
received in the car, but the command is not executed in the
bash.<br class="">
<br class="">
I don't know if you can send me more info about how to make the
car receive bash commands from remote connections, or how can I
send it from the NodeJs server into the bash of the car.<br class="">
<br class="">
Thanks for your time and help.<br class="">
