The FreeSK8 Robogotchi holds on to logs until you perform a sync operation with the Keep/Erase checkbox set to Erase. You can also perform a sync operation and leave the logs on the Robogotchi in case you want to sync with multiple devices. I imagine this will change in the future if we add cloud support.
There is enough functionality in the communication with the Robogotchi to actually display another list of files that are not yet on the mobile device. Allowing the user to select which logs they want to sync. So more of an actual file manager for what is on the receiver.
We also added a Real-time Clock w/ a supercap that functions as a 60-day battery backup for keeping time (recharged instantly each time you power on your board).
When you log over Bluetooth you can rely upon your phones clock to tell you the time so that your logs have a reference time.
With an Asynchronous logging system like this, itās possible for you to take numerous rides over a week and then sync up at a later time. The RTC allows the Robogotchi to keep time without the phone connected or even board power.
Have you tested the behavior of this on a VESC with a low power sleep mode (i.e. VESC6 MK3)? If not, I just so happen to have such VESCs at my disposalā¦
Thatās correct, thereās also a GPS module upgrade port which would also have an RTC, but not everyone is going to have the GPS upgrade + we want the Robogotchi to be fully functional by itself.
We also have the FreeSK8 NRF52 BLE module, which serves as a drop-in upgrade for existing NRF dongles. Higher power transceiver + external antenna option. Should be ready at the same time as the Robogotchi.
So the start/stop of recording is triggered by switching on/off the board?
I heard there was a guy in Portland who didnāt switch off his board for months. In this case the data logger would just keep recording till there is no space left to save data, right?
Edit: still donāt get it or canāt find the information, so I do ask the shameless question to get my understanding updated.
What you mean with ideal state? The logger will switch off the recordings automatically when the speed is 0km/h for a while? Or how to understand that.
