RAK811 - Vague Development? or Not?
I have been struggling with the following LORA nodes: RAK811 break board, RAK811 Tracker Board and RAK815 BLE Board. My doubt is that is there as any pin difference between the RAK811 Break out board node and the RAK811 Tracker Board pinout. If so can someone share it?
My next query is that even though the chip itself has 34 pinouts but gets reduced to 20 pins and some of the pins like SPI enabled pins are not available. I know that the SPI interface is done between the stm32L15X chip to sx127X chip but as per the protocol, the SPI can support more than one device. If there is any specific reason between it, please let me know.
The next thing is to make it easier for coding I had ported RAKWireless under stmduino and I am able to program it to use the pins in Arduino IDE. But after doing a lot of research, I found out that there is no Lora Mac layer library fro develop RAK811 using Arduino IDE. It would be great if there is such library well documented similar to LmIC library by IBM for this half-fried node.
Maybe you can refer to the source code of RAK811 for porting to Arduino IDE: https://github.com/RAKWireless/RAK811_LoRaNode
There are RAK811 Break Board and RAK811 Tracker Board datasheet on our websit, and you can download them to check pinout define:
I had already gone through it ,the thing is jumper lane in RAK811 break out and tracker board are not the same . I had made a comparison pinout. Pls check it and correct me if I am wrong.
