I have a LoRa based project as well. I have seen Bill's videos and they are interesting showing how the system of several boards communicate. LoRa is amazing what it does. Decoding a transmission with the signal 22db below the noise. There are many calculations to do in order to decode a signal which would bring your typical microcontroller to its knees. Fortunately Fast Fourier Transform, FFT, resolves the data in a very efficient manner. My project will be a peer to peer system using Reyax RYLR998 modules, and they do all the LoRa encoding and decoding being transceivers. sunnyboy69 you might look into that module and see if it has the range you need in your application and take your project off the Network Bill used. Reyax supports 10 , 12 , maybe more addressable units in your P2P system. It uses a cellular phone type of command structure called AT codes. You can connect the device to a UART module to a computer USB port and type in commands and SETUP information (that I believe is stored in Flash). Don't hold me to that, but it would make sense setup doesn't need continual updating. YouTube that device and watch the video there. Direct P2P is much faster than going through LoRaWan. Which reminds me, you can set the bandwidth on the modules. Narrow bandwidth = Fast speed but higher chance of bit error, wide bandwidth = slower speed but nearly 0% bit error given the same conditions. I'd like to see more done with this thing. Range up to several km out in the country.

Hi,

It's been a while since we last saw you. If you want to get that LORA sketch to work with two buttons/leds, just either send me a copy of the ORIGINAL sketch you want to modify in an attachment or in a post. I think the last time I was confused over which post to modify.

First computer 1959. Retired from my own computer company 2004.
Hardware - Expert in 1401, 360, fairly knowledge in PC plus numerous MPU's & MCU's
Major Languages - Machine language, 360 Macro Assembler, Intel Assembler, PL/I and PL1, Pascal, Basic, C plus numerous job control and scripting languages.
My personal scorecard is now 1 PC hardware fix (circa 1982), 1 open source fix (at age 82), and 2 zero day bugs in a major OS.
