Hi there!
I am attaching a real example of Semtech UDP packets used recently this morning (that is to say, both the rxpk and the stat, which are related to the first communication steps):
/*******************************************************************************************/
Stat
{“time”:“2020-10-29 08:29:44 GMT”,“lati”:0,“long”:0,“alti”:0,“rxnb”:0,“rxok”:0,“rxfw”:0,“ackr”:100,“dwnb”:0,“txnb”:0}
Rxpk
{“time”:“2020-10-29T08:29:47.678004Z”,“tmst”:1603956587,“powe”:14,“chan”:0,“rfch”:0,“freq”:868.1,“stat”:1,“modu”:“LORA”,“datr”:“SF7BW125”,“codr”:“4/5”,“rssi”:-35,“lsnr”:5,“size”:46,“data”:“AO/Nq5B4VjQSAJmqu8zd7v/Me0zhInc=”}
Stat
{“time”:“2020-10-29 08:32:06 GMT”,“lati”:0,“long”:0,“alti”:0,“rxnb”:0,“rxok”:0,“rxfw”:0,“ackr”:100,“dwnb”:0,“txnb”:0}
Rxpk
{“time”:“2020-10-29T08:32:08.878004Z”,“tmst”:1603956728,“powe”:14,“chan”:0,“rfch”:0,“freq”:868.1,“stat”:1,“modu”:“LORA”,“datr”:“SF7BW125”,“codr”:“4/5”,“rssi”:-35,“lsnr”:5,“size”:46,“data”:“AO/Nq5B4VjQSAJmqu8zd7v9wb/g86W0=”}
Stat
{“time”:“2020-10-29 08:32:38 GMT”,“lati”:0,“long”:0,“alti”:0,“rxnb”:0,“rxok”:0,“rxfw”:0,“ackr”:100,“dwnb”:0,“txnb”:0}
Rxpk
{“time”:“2020-10-29T08:32:41.766004Z”,“tmst”:1603956761,“powe”:14,“chan”:0,“rfch”:0,“freq”:868.1,“stat”:1,“modu”:“LORA”,“datr”:“SF7BW125”,“codr”:“4/5”,“rssi”:-35,“lsnr”:5,“size”:46,“data”:“AO/Nq5B4VjQSAJmqu8zd7v/d1L8pvIA=”}
Most information has been made up, but I tried to simulate them with random values achieving the same wrong result.

I hope this helps, if you need further information please, do not hesitate and ask for it, I will be glad to share it!
Thanks beforehand, looking forward to hearing from you.
Kind regards.
