Airspy SDR verifies that #BL602 is indeed transmitting the Join #LoRaWAN Network packet ... Maybe it contains garbage 🤔

Here's the #BL602 "Join Network" #LoRa Chirp ... Recorded by Airspy SDR with CubicSDR

Here's the "Join Network" #LoRaWAN Packet transmitted by #BL602 ... Does this look right? 🤔 Let's compare with WisBlock

https://github.com/lupyuen/bl_iot_sdk/tree/lorawan/customer_app/sdk_app_lorawan#output-log

#LoRaWAN "Join Network" Packet transmitted by #WisBlock ... Looks similar to the one transmitted by BL602 ... Nonce and Message Integrity Code will differ of course

https://github.com/lupyuen/wisblock-lorawan/blob/master/README.md#output-log

Here are the #LoRaWAN Packets transmitted by RAKwireless #WisBlock ... Captured by Airspy SDR and CubicSDR

https://youtu.be/xdyi6XCo8Z8

#LoRaWAN Packet: #BL602 vs #WisBlock ... Seems BL602 is transmitting at Lower Power than WisBlock ... Let's check the Power Amplifier settings 🤔

https://github.com/lupyuen/bl_iot_sdk/tree/lorawan/customer_app/sdk_app_lorawan#output-log

#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

For Reference: Here's how I connected #PineCone #RISCV #BL602 @PINE64 to Pine64 RFM90 #LoRa Module (SX1262)

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! 🙄

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

https://github.com/lupyuen/bl_iot_sdk/blob/lorawan/customer_app/sdk_app_lorawan/README.md#lorawan-commands

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

https://youtu.be/BMMIIiZG6G0

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