Hey,
I am having problems with the Lambda to CAN again. problems are different than before, but it never worked perfecty for me.
I have only Lambda to CAN and CAN BT on my CAN circuit and I have added one 120 ohm resistor, one from emu is on. I am using CAN speed as 500kbps because of the BT module, and I have changed the Lambda to CAN to work with that speed too. However the Lambda to CAN sometimes changes the speed back to the original 1Mbps and then it stops working, if I dont change the CAN speed to 1Mbps, but then BT doesnt work, then I need to change Lambda to CAN back with light client which doesn’t make any sense, why does it do this?
I shared log here where the problems can be seen. Also sometimes the lambda 2 reads weird numbers in the log. Sometimes its reading 0.82 for long times, then suddenly it goes to reading number as high as 10-15. Sometimes I get it to work when I restart the car, sometimes it just stars randomly working.
In the log around 41:30 the lambda to CAN changes its speed from 500kbps to 1Mbps and CAN log channel starts to show error. Also other weird stuff is showing in the log.
I’m also sometimes having hard time to get the Lambda to CAN show up on the Light client, then I just turn the power on and off many times and it will eventually start to show up. I tried to update firmware and reset it many times, but it doesnt remove the problems. I have remove error flags, on from light client, and also change all CAN devices to this speed (500kbps) as default.
IF the bluetooth could use 1Mbps speed I guess I could use it but since it doesnt its pain in the ass. Is there any other oprion than buy new one?
I Am running v3 3.056 at the moment.
