Yep "pbuf" from the #BL602 Lightweight IP Stack can be used instead of Mbuf ... We just need to shift the Header / Payload Pointer to work on #LoRaWAN Packets

...Which explains why so many folks at STMicro are now reading this #BL602 #LoRaWAN Thread

😉

Here's a friendly doc by STMicro that explains MCPS Messaging in our #BL602 #LoRaWAN Driver

#BL602 IoT SDK has a "pbuf" in the lwIP Lightweight TCP/IP Stack ... Maybe our BL602 #LoRaWAN Driver can use this instead of Mbuf? 🤔

https://github.com/lupyuen/bl_iot_sdk/blob/lorawan/components/network/lwip/src/include/lwip/pbuf.h#L185-L222

What's an Mbuf? Why is it used by our #BL602 #LoRaWAN Driver? Mbufs are Chains of Fixed-Size Blocks ... Works great with little RAM (no fragmentation) ... Created for BSD Unix in 1983!

https://mynewt.apache.org/latest/os/core_os/mbuf/mbuf.html

Uh-oh our #BL602 #LoRaWAN Driver (from Mynewt) passes LoRaWAN Packets in Mbuf Format ... Let's find something equivalent on BL602 🤔

https://github.com/lupyuen/bl_iot_sdk/blob/lorawan/components/3rdparty/lorawan/src/lora_app.c#L260-L303

Curiously, our #BL602 #LoRaWAN Driver includes a Command-Line Interface (bottom) that Transmits and Receives LoRa Packets ... Directly calling the SX1276 Driver 🤔

How shall we implement the #BL602 #LoRaWAN Event Queue for the Medium Access Control Layer? With the NimBLE Porting Layer of course!

The #LoRaWAN Protocol is explained in this thread: Encryption, Receive Window, Duty Cycle, ...

https://qoto.org/@lupyuen/105874847933603494

The Medium Access Control Layer (right) of our #BL602 #LoRaWAN Driver implements the LoRaWAN Protocol: Encryption, Receive Window, Duty Cycle, ... It exposes the MCPS Messaging Interface (IEEE 802.15.4) to the Node Layer (centre) via an Event Queue
