Now we port the #LoRaWAN Driver ... From Apache #Mynewt OS to #BL602
https://github.com/lupyuen/bl_iot_sdk/tree/lorawan/components/3rdparty/lorawan
Our #BL602 #LoRaWAN Driver has many Layers (like Shrek) ... Let's peel the Shrek ... (erm) Layers 🧅
https://github.com/lupyuen/bl_iot_sdk/tree/lorawan/components/3rdparty/lorawan
The Application Layer (left) of our #BL602 #LoRaWAN Driver exposes LoRaWAN Functions to Application Firmware ... Join Network, Open/Close Port, Transmit/Receive Packets
https://github.com/lupyuen/bl_iot_sdk/blob/lorawan/components/3rdparty/lorawan/src/lora_app.c
#Mynewt OS has a #LoRaWAN Command-Line App that calls the Application Layer of the LoRaWAN Driver ... We shall port this app to #BL602 too
https://mynewt.apache.org/latest/tutorials/lora/lorawanapp.html
For #Arduino Fans: RAKwireless has a #WisBlock #LoRaWAN Tutorial ... We shall try this later
https://github.com/RAKWireless/WisBlock/tree/master/examples/communications/LoRa/LoRaWAN
The Node Layer (centre) in our #BL602 #LoRaWAN Driver handles the networking operations for our BL602 LoRaWAN Node ... It's called by the Application Layer (left)
https://github.com/lupyuen/bl_iot_sdk/blob/lorawan/components/3rdparty/lorawan/src/lora_node.c
What's MCPS in the #BL602 #LoRaWAN Driver? ... That's the "MAC Common Part Sublayer", which is defined in the Semtech LoRaWAN Stack
https://stackforce.github.io/LoRaMac-doc/LoRaMac-doc-v4.4.7/index.html
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
https://github.com/lupyuen/bl_iot_sdk/blob/lorawan/components/3rdparty/lorawan/src/mac/LoRaMac.c
The #LoRaWAN Protocol is explained in this thread: Encryption, Receive Window, Duty Cycle, ...
How shall we implement the #BL602 #LoRaWAN Event Queue for the Medium Access Control Layer? With the NimBLE Porting Layer of course!
https://lupyuen.github.io/articles/lora2#multitask-with-nimble-porting-layer
Curiously, our #BL602 #LoRaWAN Driver includes a Command-Line Interface (bottom) that Transmits and Receives LoRa Packets ... Directly calling the SX1276 Driver 🤔
https://github.com/lupyuen/bl_iot_sdk/blob/lorawan/components/3rdparty/lorawan/src/lora_cli.c
Porting pbuf Packet Buffer Queue from Mynewt OS to #BL602 ... Makes me hungry for Peanut Butter Jelly Sandwich 🤤
https://github.com/lupyuen/bl_iot_sdk/blob/lorawan/components/3rdparty/lorawan/src/pbuf_queue.c
Using this simpler Windows CMD script to build the #BL602 #LoRaWAN Driver ... Quicker for fixing build errors
https://github.com/lupyuen/bl_iot_sdk/blob/lorawan/customer_app/sdk_app_lorawan/run.cmd
Add the "c_cpp_properties.json" file to #VSCode ... So that our #BL602 #LoRaWAN Build Errors are highlighted
https://github.com/lupyuen/bl_iot_sdk/blob/lorawan/.vscode/c_cpp_properties.json
Reference Implementation of Semtech #LoRaWAN Stack is here ... Includes drivers for SX1262 and SX1276
Bought the RAKwireless #LoRaWAN Gateway: #WisGate Developer D4H ... Will benchmark this with #Pine64 LoRa Gateway (Also based on RAKwireless RAK2287)
https://docs.rakwireless.com/Product-Categories/WisGate/RAK7248/Datasheet/
#ChirpStack on RAKwireless #WisGate can generate random Application Keys for #LoRaWAN Over-The-Air Activation (OTAA) ... We shall use keys to activate our #BL602 and #WisBlock devices wirelessly
https://www.thethingsindustries.com/docs/devices/abp-vs-otaa/
Something (or Someone) is transmitting #LoRaWAN Packets every minute ... Signal Strength (RSSI) shows that they're a few hundred metres away
https://gist.github.com/lupyuen/8dacf002196507695a7624ef7f80a34f
Based on earlier #LoRa Coverage Testing (with #BL602 and #WisBlock) ... High chance that our Mystery #LoRaWAN Transmitter is at the nearby Subway Station 🤔
https://lupyuen.github.io/articles/wisblock#analyse-the-lora-coverage
Someday I might walk around with RAKwireless #WisGate to find the Mystery #LoRaWAN Transmitter ... But for now let's test WisGate with WisBlock and BL602!
https://docs.rakwireless.com/Product-Categories/WisGate/RAK7248/Datasheet/
Still fixing #LoRaWAN Driver for #BL602 ... So let's test WisGate with WisBlock first
https://github.com/lupyuen/bl_iot_sdk/tree/lorawan/components/3rdparty/lorawan
#LoRaWAN Driver for #BL602 ... One last build error
https://github.com/lupyuen/bl_iot_sdk/tree/lorawan/components/3rdparty/lorawan
#LoRaWAN Driver for #BL602 ... Builds and links OK yay! 🎉 Heading out for second dose of Moderna ... And some downtime
https://github.com/lupyuen/bl_iot_sdk/tree/lorawan/components/3rdparty/lorawan
Let's test RAKwireless #WisGate with #WisBlock ... With this #Arduino #LoRaWAN program ... Once I get home from vaccination
https://github.com/RAKWireless/WisBlock/tree/master/examples/RAK4630/communications/LoRa/LoRaWAN
#WisBlock #LoRaWAN sample fails to compile ... Let's find out why 🤔 (Hope it's not because of the vaccination)
https://github.com/lupyuen/wisblock-lorawan/blob/master/src/main.cpp
@lupyuen
Cool code Prof. Much success. Btw what os is new platform youre porting to? Old one was this apache newt right?
@lupyuen
You need to think of secu now. Who is and who isnt allowed on the net. Either no entrance from blacklist or whitelist guests only allowed.
@lupyuen
One more hint. Try to measure signal strength and drive around with detector and record gps plus power detected.
That should help to narrow it down.
Good luck.
We verify that #BL602 "pbuf" Packet Buffers can handle a full #LoRaWAN Packet ... Header: 20 bytes, Max Payload: 255 bytes
