I have a bunch of Electrons with me and I’m planning to make them connect to MY server in order to make further evaluations.
In my scenario (France) the price is 0.40€/MB.
I found that I can send UDP packet from the Electron but I’m not sure how much is the final price.
Let’s say I need to send a 50byte string, then a packet will be: 8byte UDP header + 20byte IP header + 50byte payload: 78byte.
14285 UDP packets/month
0.40€/3 months sending 1 packet every minute
If I understood correctly, I have to consider ‘handshake’s cost’. Does it happen everytime I turn the Electron on? My plan is get the sample, sleep 60sec than awake and sample again.
That mean an handshake every minute? 6kB every minute more?
Does it exist a function that put MCU to sleep, but keeps cell/connection information?
Does the handshake happens every 23min anyway? (with Particle sim)
Note: I’ve already read https://docs.particle.io/tutorials/cellular-connectivity/data/ but I still have the doubts above.
