Oops Mynewt's #LoRaWAN Carrier Sensing implementation is outdated ... Semtech's LoRaWAN Reference Implementation does NOT require Carrier Sensing outside Japan and South Korea ... So we disable Carrier Sensing and use a random LoRa Frequency Channel
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 🤔
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
#LoRaWAN AS923 Region Settings look different across the 3 LoRaWAN Stacks 🤔
