Arduino - TypeError: Cannot set property 'mode' of undefined

[DarekLin]

Hello, I would like to run communication with Arduino Uno via hosted node-red on beaglebone black and base on node-red-contrib-gpio but i can't. When I try to send "1" to 13 pin I received:

root@beaglebone:~# node-red-pi

On the arduino I have install standardFirmata. On the node-red the gpio module flash green so coonection to serial seems to be ok. Could you help me?

Sorry my mistake. I didn't assigned pin (;

I seem to be getting the same issue but in my case, I have defined a Pin. I am using CHIP as my board ... here is my current flow:

[{"id":"1ce0da90.705275","type":"gpio out","z":"93e6f36a.1d1aa","name":"","state":"OUTPUT","pin":"\"XIO-P0\"","i2cDelay":"0","i2cAddress":"","i2cRegister":"","outputs":0,"board":"e735b9b7.bd9d68","x":396,"y":196,"wires":[]},{"id":"e735b9b7.bd9d68","type":"nodebot","z":"93e6f36a.1d1aa","name":"","username":"","password":"","boardType":"chip-io","serialportName":"","connectionType":"local","mqttServer":"","socketServer":"","pubTopic":"","subTopic":"","tcpHost":"","tcpPort":"","sparkId":"","sparkToken":"","beanId":"","impId":"","meshbluServer":"https://meshblu.octoblu.com","uuid":"","token":"","sendUuid":""}]

and here is the log from Node.RED:

Aha!!! Solved the problem by running the node.js debugger and stepping through. I had coded:

"XIO-P0"

as my pin name when what I should have coded was:

XIO-P0

i.e. no quotes. Changed in my flow and all is now well.
