I am prototyping a device controller using an Arudino Uno and an XBee S6B (latest firmware). My goal is to have a 110 byte UDP packet sent out every second. Part of the device interaction with the outside world is the duration of time that has past since the controller was turned on, so a packet every second is ideal.
I realize that occasionally packets may drop, so I actually send out a packet every 500ms, but what I see occasionally is that I have random times where out of nowhere the packets disappear for upwards of 10 seconds.
I ran a long test and while the delay varies from 2 seconds to 10 seconds, over the course of a half hour roughly 5 % of the packets I send get lost.
I’ve tried using different wifi networks, different send times, different baud rates, etc. I can’t seem to find any consistent improvement.
Is there something I could check for to solve this mystery?
I don’t mind losing an occasional packet but having the device not talking randomly for 5 to 10 seconds here and there is a big problem.
