Void write(const byte message, byte size). I think things are choking when trying to do ibus.write(debugSerialSend, sizeof(debugSerialSend)) due to the fact that ibus.write is expecting a 'const byte' and my dynamically created array is just byte. I'm successfully creating a byte array and populating it with the data that I'm sending over Serial1 ( byte debugSerialSend) I can print the populated array elements afterwards and can see that it's the correct size and with the correct data. I'm a ruby guy and this project is my only experience with C++. My next step is to send messages via Serial1. I'm using a USB breakout for on Serial1 and I can see all the debug messages fine. I'm using the The TH3211.4 chip with an arduino mega, I can send and receive ibus messages on my E46 and have set up some basic automation already (Folding/unfolding mirrors when locking/unlocking the car). I have got huge chunk of this project working, using Ibus Library V2. So I'm assuming K/iBus is only accessible when connected to the actual vehicle? but when I tried this with the Resler, I get nothing. When testing CAN Bus stuff of course, I can use 2 can bus devices to talk to each other to test hardware and coding etc. (And then also send/receive between them) So basically, If I were to join 2 Resler USB Devices together joining the K wire - could I use NavCoder to SEND messages, for example via the MFSW Emulator part, and then for arguments sake, lets assume the 2nd Resler device is using NavCoder on a second computer - can I have that NavCoder in Live Stream mode, and see the k bus stuff the first is sending. Is it possible to make 2 Resler devices talk to each other for testing? I also have a Resler USB v6 and have had a look with NavCoder and done some logging etc.Įxcuse my dumb question now, I've done all sorts with CAN Bus stuff and dozens of other MCU related stuff, however this is my first attempt at doing anything iBus related. I'm using the Arduino Nano (for now) and I've made my own PCB using the TH3122.4. Apologies for digging up an old thread, but I'm building myself an I/KBus circuit.
