#BL602 joins the #LoRaWAN Network ... And transmits a data packet

#LoRa Concentrator Doc made me wonder ... Could our #LoRaWAN Gateway be dropping packets from #BL602 because we sent the wrong Sync Word? Yep indeed!

Here are the tested #LoRaWAN Commands for #BL602 to transmit data packets correctly to the WisGate ChirpStack LoRaWAN Gateway 🎉
