Like royhen99 said the pin 32 is low side switch so your relay needs a positive on the coil.

"If you're having trouble connecting using the serial interface, note that the parameters are 115200 8-N-2, which is different from the conventional 115200 8-N-1. "

I finally go my shunt communicating to VCU! I have the IVT-S-1K-U3-I-CAN2-12/24. I changed the parameters to communicate can2 and could not get it to work changed it to can1 and now works. When doing the initialization the drop down has on off and NA as options now am i to assume the NA is ...

In my testing today i had GPIO set to 1 and held down the button on power up and it puts it in program mode it also mentions it in the Olimex documentation if you don't have the button you need to move the jumper. No need to move solder jumper every time. ?an any one try this and see if it works for ...

Tested a few times with susses.
Board: "generic Esp8266"
Build:2
upload speed 115200

The rest of the settings the same as wiki.

I had the same problem with the wifi module every time i tried the Arduino flash process it would fail then i changed the board to "Generic ESP8285" it worked but it is not that board. I'm going to try using the "Generic ESP8266" to see if that one works. I cannot get the wiki instruction olimex mod ...

Same problem. I followed instruction to a T. Flashing goes fine in arduino IDE. After I solder back the GPIO0, the only wifi network to show up is ESP-XXXXX.
I'm getting sick of soldering this jumper over and over.


I put wires on power ground and on the non ground side of the button ant removed ...

I just figured out how to re flash but it gives me the same problem every time i do it. I'm thinking the modal is bad.

Need help with wifi got zombieverter vcu parts populated and power up test but when adding the wifi olimex esp8266 board has solid green and solid red led. I attached to serial cable and the Arduino monitor shows "sec 1fd error" constantly outputting.
