Start/Stop recording and Wakeup Action4/5 (like GPS Remote)?

[danergo]

Is this something achievable?

GPS Remote can do that, but I'm looking for an opensource implementation.

Your description caught my eyes, but I can't find more details. Please confirm this.

[danergo]

scan-for-devices.js works, finds my Action4.

Now how can I start recording?

[datagutt]

Feature list does not have recording as a feature. I am lacking additional documentation of the protocol when it comes to recording etc

[danergo]

I have a GPS Remote from my friend for a week. I also have a BLE sniffer (TI), which can record pcap to analyse with wireshark. In case I do some logs (start and stop record), would you mind helping to analyze them?

[danergo]

Hardest thing IMHO is the linking process, which is already done (my Action4 displayed 'love'), so a few basic commands (start/stop record, turn off, wake up, quickswith pushbutton trigger) shouldn't be hard to detect for a trained eye. All these functions are in the GPS Remote, so I can trigger these functions many times to reproduce in the logs. Let me know your thoughts :)

[danergo]

What do you think?

[datagutt]

Logs are welcome

[danergo]

Here we go:

Action4.zip

[danergo]

This contains:

• pairing procedure
• start recording
• stop recording

Then a few more start/stop,

Then power off command, then wakeup command.

Did you have any luck with it? Would you like having more, specialised logs? (Like only start, only stop, etc)? If so - let me know.

I appreciate your help.

Thanks!

Hi! Do you have any news maybe? Let me know how can I help.

[danergo]

I will need to give back the GPS Remote to my friend soon. Please let me know if any other logs will be needed to record.

Thank you!

Havent had time to start the actual implementation, but this should be fine to start

[danergo]

Thanks a lot!

Once we will succeed replaying these commands, I will port this to WearOS, so we can use our smartwatch to control these cameras. Also, I'll create a physical remote, which will work with both cameras, similar to GPS remote, but smaller, and more stable (battery, screen, few buttons). Will be very nice :)

That would be very useful, a DIY remote to start/stop recording

[danergo]

Yepp. Will definitely do once we can could reverse engineer these commands. :)
