I can't seem to update my CBT's firmware on my Ubuntu machine. I've tried both the alpha app, as well as through the Arduino sketch, with no luck. The LED on my CBT goes from flashing red slowly, then flashing red quickly, then just green but that alpha app stays on the flashing in progress screen. If I try updating through Arduino, I get "avrdude: ser_open(): can't open device "/dev/ttyACM0": Permission denied
avrdude: ser_send(): write error: Bad file descriptor". I've done some searching for this error on Arduino as a whole and have seen some issues related to USB 3.0. Unfortunately my laptop only has 2 USB ports, and they're both 3.0 ports.
Hey guys, I'm Joel from southern California. I've dabbled a bit with arduino and have done sniffing on CAN, but have never gotten around to building anything to interface with and send packets on it. I'm looking forward to using the CBT I received as my backer reward to control some convenience features on my W204 using my phone like locks, windows, etc. Now to find the time between work and school!
Not to continue the off-topic Mitsu discussion, but it looks like there is indeed a gateway setup in that as well. The ETACS-ECU serves as the gateway between the middle speed, high speed and diagnostic CAN networks. Looks like most of the interesting stuff (convenience, infotainment, etc.) is on the middle speed CAN-B network, so you'd have to tap into that bus at any of the ECUs on that bus, such as the radio or combination meter.
