Browse files Browse the repository at this point in the history
### Initial Releases v1.0.0

1. Initial coding to support **nRF52-based boards, such as AdaFruit Itsy-Bitsy nRF52840, Feather nRF52840 Express, Seeed XIAO nRF52840, Seeed XIAO nRF52840 Sense**, etc. using [`Adafruit nRF52 core`](https://github.com/adafruit/Adafruit_nRF52_Arduino) or [`Seeeduino nRF52 core`](https://github.com/Seeed-Studio/Adafruit_nRF52_Arduino)

/*
Udp.cpp: Library to send/receive UDP packets.
NOTE: UDP is fast, but has some important limitations (thanks to Warren Gray for mentioning these)
1) UDP does not guarantee the order in which assembled UDP packets are received. This
might not happen often in practice, but in larger network topologies, a UDP
packet can be received out of sequence.
2) UDP does not guard against lost packets - so packets *can* disappear without the sender being
aware of it. Again, this may not be a concern in practice on small local networks.
