I have a GH505 since 2010 and still use it...
However, I recently tried to use it indoor (to record time and HR) but I can't get it to work... it records 1 point and that's it...
I have Firmware-F-GGH-2C-1010221
I saw some messages about indoor use but can't figure out if that was ever implemented or in beta?
Is it possible to record HR during indoor activity? If not, is there a beta firmware that would allow me to do so?
