#BL602 vs #WisBlock: Join #LoRaWAN Network Request ... Let's check the Nonce and Message Integrity Code ... Wonder if we can retransmit the BL602 packet from WisBlock 🤔
https://github.com/lupyuen/bl_iot_sdk/tree/lorawan/customer_app/sdk_app_lorawan#output-log
Let's copy the Join #LoRaWAN Network Request generated by #BL602 ... And retransmit with #WisBlock ... Surprise: the Join Request succeeds! 😲 Which proves the Nonce and Message Integrity Code are OK ... Probably the BL602 Power Amplifier setting is wrong 🤔
https://github.com/lupyuen/bl_iot_sdk/tree/lorawan/customer_app/sdk_app_lorawan#output-log
But wait: Will #LoRaWAN allow replayed "Join Network" Requests? 😲 Nope it doesn't! #WisGate #ChirpStack will reject Replayed Requests because the Nonce needs to be unique ... Here's how we find Nonce Errors in RAKwireless WisGate
Taking a short BL602 break ... To write about everything I've done with #RAKwireless #WisGate

#WisGate #LoRaWAN Gateway receives LoRaWAN Data Packet from #BL602 yay! 🎉
https://github.com/lupyuen/bl_iot_sdk/blob/lorawan/customer_app/sdk_app_lorawan/README.md#output-log
We should always select "Public LoRa Network" (instead of Private) ... So that our #BL602 #LoRaWAN Driver will transmit Public Sync Word 0x3444 (instead of 0x1424) ... Duh! 🙄

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

#BL602 transmits a packet to #LoRaWAN Gateway and receives the response ... Why is BL602 transmitting at Lower Power, when the Power Amplifier is enabled? 🤔
