Byte order of data in LoRa packets sent by IUWS water meter
Hello,
On the document “Lora radio packet definitions” v1.34, it states that big endian is used (chap 2.2, “If not specified differently, byte order will be MSB first.”)
And on the “IUW-IUWS User guide for system integrators” v1.9, there are some LoRa packet examples on page 41. And in these, it appears that little endian is used to encode the water meter data.
But I cannot find anywhere written that the water meter sends its values in little endian. It does match the payloads we are receiving, so most likely it is little endian. However, I have a doubt about the timestamp and the state stamps. Are they sent also in little endian ? Or is big endian used ? Because the examples on page 41 do not show the decoded value of the timestamps.
