Why #BL602 "pbuf" is OK for handling #LoRaWAN Packets

https://github.com/lupyuen/bl_iot_sdk/blob/lorawan/customer_app/sdk_app_lorawan/sdk_app_lorawan/pbuf.c#L96-L183

We verify that #BL602 "pbuf" Packet Buffers can handle a full #LoRaWAN Packet ... Header: 20 bytes, Max Payload: 255 bytes

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

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