There will soon be available a binary protocol for larger data transfers to the modem: https://github.com/blues/note-c/blob/master/n_helpers.c#L108 https://dev.blues.io/blog/send-receive-binary-files-notecard/

With the new binary protocol (#150 ) it might be possible to send higher frequency data. The IMU has 16bit resolution on each 6 components. So compared to now (52...

Depending on how the IMU works. It might be useful to low-pass filter the signal to avoid saturation. Something like this can be used: https://github.com/OpenAcousticDevices/AudioMoth-Firmware-Basic/blob/master/src/butterworth.c (similar to what we do...

With #114 it is possible to set up sfy-data with postgres and kubernets. we're hitting some limits w.r.t scaling and backup of disk-space. the server is stateless so it is...
