Sending parts of learning sensor data to server each time #184

Closed IoTThinks closed 3 years ago

IoTThinks commented 4 years ago

Hi all, I'm sending the sensor data via long range signal (LoRa 433Mhz) to gateway (has wifi) then to find3 server. The long range signal has maximum 256-character message each time.

Let say I learn 9 sets of SSID and RSSI during learning. So if I send 3 sets of SSID and RSSI each time. And send multiple time until finish.

  1. Will it impact the tracking accuracy? Or it is a must to send them at one go?
  2. Can I send "lora" as sensor data besides "wifi" and "bluetooth"?

Thanks a lot. Have a nice day.

I guess can use justsave as mentioned in https://github.com/schollz/find3/issues/49 Send parts and parts of sensor data then compute later.

Will give it a try.

Confirmed not working as expected if I break the fingerprinting message in to multiple smaller messages, Each message is considered a fingerprinting on their own.

Can use passive scan. It works with multiple small messages.
