Hi there,
I’m using a RAK831 concentrator over a raspberry pi 3. After some code changes which I found in this forum, I achived to improve the accuracy of the field “time” into the gateway ( I have an accuracy of nanoseconds). So far, so good.
The problem that I’ve found out in some packets ( around 20% of them) is that packets lose 3 digits of accuracy. These packets have 000 in the last 3 digits. I know that it could be a possibility, but it happens often, so I’m sure there is another problem there.
Packet with 9 digits accuracy:
{“rxpk”:[{“tmst”:2661074596,“time”:“2020-01-17T12:41:13.757927757Z”,“chan”:6,“rfch”:1,“freq”:918.000000,“stat”:1,“modu”:“LORA”,“datr”:“SF7BW125”,“codr”:“4/5”,“lsnr”:9.2,“rssi”:-48,“size”:23,“data”:“QEQYAyaABQAB15NgexkO+nRB9I20tn4=”}]}
Packet with 6 digits accuracy:
[{“tmst”:2723351956,“time”:“2020-01-17T12:42:16.035314000Z”,“chan”:7,“rfch”:1,“freq”:918.200000,“stat”:1,“modu”:“LORA”,“datr”:“SF7BW125”,“codr”:“4/5”,“lsnr”:10.2,“rssi”:-73,“size”:23,“data”:“QEQYAyaABgABb8G1UbonwA86LDJ1tD8=”}]}
Thanks for any hint!
