I am trying to optimize my data usage for an Electron device and have noticed the following usage: 10 days: 0.67mb of data My Electron is publishing an event every 5 minutes called “Temp” with values similar to “71,53,97,0”. That’s approximately 10 bytes of data. Where is the rest of my data usag…

[image] BDub: @RWB up to half comes from the observed effect that every publish of just one byte is about 61 bytes of data usage (data, encryption and overhead). Also there are about 61 bytes received for the ACK. So if your payload is large, it starts to be less than half since the ACK doesn'…

@BDub , could you quote the exact statement you are refering to? I guess you might have misunderstood what I meant, or I haven't expressed myself well. When I said [image] ScruffR: With NO_ACK you'll save all the extra attempts, since it's fire and forget I thought I've actually stated the …

[image] RWB: I know you were working on reducing the frequency that the Electron needed to handshake or ping the cellular server which in turn reduced the amount of data used over the course of a day. Can you also point me in the right direction when it comes to this? Try soft powering down …

[image] BDub: Try soft powering down a 0.6.0-rc.1 electron by double tapping the setup button. This is effectively deep sleep. Then press reset. Notice how fast it connects. No handshake! It's resuming the previous session. I just found this in the 0.6.0 firmware update reduce datausage o…

I would advise using it as described… I may have misspoke about the soft power down… I swear I was just using it that way though and it was powering up super fast (blinking green and cyan in a couple seconds). Now that I’m trying it again it’s going through a long connection process (blinking green…

[image] BDub: when you said this sentence, it made me believe you typically experience every publish require 2 retry events. That should not be the case and I wonder why it is for you. No, I don't see that at all! With "up to 2/3+" and the subsequent condition, I was just refering to the po…

Ok cool… to be fair the retry can happen 5 times before it resets the network connection which will then also force a full handshake… so it goes from data savings up to half down to like zilch if you have connectivity problems, but that won’t be any fault of the NO_ACK option :wink: Perhaps the ben…

@Bdub @ScruffR I used MDMA’s code for testing the data transfer rates on the Electron using the NO_ACK vs. not using it and I came up with the following results. I was just checking the data usage updates on the SIM Card Billing page, but its resolution was too small to see what was going on. Here…

@BDub @mdma Quick question about: [m-mcgowan] reduce datausage on reset/wakeup by m-mcgowan on 04:29PM - 11 Apr 16 6 commits changed 21 files with 420 additions and 57 deletions. Does this work with any Deep Sleep time frame? Like d…

@RWB , as PR #953: Reduces data consumption when the device is reset or wakes up from deep sleep.
