Did you find solution for this?

To update you guys on this, apparently SoftwareSerial uses delays in its interrrupts (which is a pretty bad coding practice), which makes it incompatible with most Interrupt-Based Libraries, like this one. You can read more about it here, but the TL;DR of all this is to stop using SoftwareSerial and try using its counterpart AltSoftSerial if you aren't using all of your Arduino's timers. If you are... I guess you're kinda cooked :p
