Ricoh GR II has a remote interface. But like most modern cameras the interface is terrible.
It’s a WiFi Access Point that uses a web app. And because most modern phones are terrible,
this means you have to juggle between WiFi that doesn’t provide an internet connection and
a web app that kinda requires it. The
Ricmohte uses an
ESP32 to connect to the cameras AP
and issue commands.
Sadly the GR II has been retired (reads: broken beyond reasonable repair). But this
ESP32button lives on as a handy dust collector remote. This project page will eventually be updated to reflect that but in the meantime the source files are posted below.
Note about the firmware: This was written while literally sick in bed. The portions for controlling
a servo where an attempt at 3d scanning that kicked off the hardware design but not actually
related to the overall project.
