			==== Received Packet Errors ====

			"Recieved Packet Errors" is a measure of how many CRC errors were present during receiving packets by the radio chip.

			# LoRa radios are very sensitive and often detect very distant transmissions - if your repeater hears a lot of those edge packets, you will get very high error counts
			# If your mesh is busy and air utilization is high, there is a much higher chance of RF collisions - that will also add to the counter of CRC errors
			# Your radio might be near other strong RF source such as a GSM/LTE tower that causes your radio to miss complete packets - it's good to use a bandpass filter in that case
			# Anything that transmits in same frequency or very close can make your radio misread packets - this is good to investigate using spectrum analyzer with a good antenna.

	'''[[Meshtastic]]''' is the older network. Meshtastic used "controlled flooding" protocol. Every client in a Meshtastic network can retransmit messages it receives from other nodes.
