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!
