#BL602 is now transmitting the #LoRaWAN Join Network Request ... But doesn't receive any response from our LoRaWAN Gateway (WisGate) ... Let's check the WisGate LoRaWAN Log

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

#WisGate #ChirpStack you're so funny ... I'm nowhere near Chinese Garden, Japanese Garden and Jurong Bird Park 😂

https://docs.rakwireless.com/Product-Categories/WisGate/RAK7244C/Quickstart/#connect-the-gateway-with-chirpstack

Let's move #PineCone #BL602 (and #Pinebook Pro @PINE64
) real close to RAKwireless #WisGate ... For our #LoRaWAN testing

https://github.com/lupyuen/bl_iot_sdk/tree/lorawan/customer_app/sdk_app_lorawan

Sadly our #WisGate #LoRaWAN Gateway didn't receive any LoRaWAN Packets transmitted by #BL602 ... Let's look inside the transmitted packets ... And verify the transmission with Airspy SDR

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

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

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

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

https://youtu.be/7a4rfaI_zV4

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

https://github.com/lupyuen/bl_iot_sdk/tree/lorawan/customer_app/sdk_app_lorawan#message-integrity-code-errors

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? 🤔
