[KettlerUSB] port is not open, retry in 10s

[laurent-web]

Hello, I've this message when i start , after sudo node server.js it 's the code from file kettlerUSB.JS, generate by line 160

internalOpen() { this.port.open((err) => { if (!err) return; console.log('[KettlerUSB] port is not open, retry in 10s'); setTimeout(() => this.internalOpen(), 10000); }); };

i don't know how to correct this error, the access at browser pi-adress:3000 is ok when i start zwift, it recognize kettlerBLE, but when i run, nothing 0 watts on browser eton zwift. Is someone can help me? Thank you. Laurent

Hello

It seems that the soft is running. Very strange !

Some ideas :: Have you been able to connect to the bike using your PC ? With GoldenCheetah or KettlerWordTour ?

Are you using a Pi Zero ? The COM port may have a different name on other models.

you can also log the error: add this : console.log(err); console.log('[KettlerUSB] port is not open, retry in 10s');

Hello! I bought an RPi ZERO WH for this. I get the same problem.

Hello

I think the problem is coming for the oled screen driver. I added a screen to display the slope and gears. It's not optional at this stage and it was sendind an exception line 100 or 103. I removed it from the code.

Tell me if it's ok

Hello,

Before starting node, i try to configure with minicom the ttyUSB0 port. i only change bauds (9600). i don't change the other settings. I start node and i hear a sound from the bike (that i do not have before) but nothing more.

i have always the message remote I/O error , write. problem wih I2C and other settings of ttyUSB0? I keep searching.

hello

I pushed a new version without i2c oled screen. It used to display a message to log some info about the serial port. But it was probably launching an exception while logging.

It doesn't mean that it works. But you can try.

Hello, I am trying to get your bridge to work with my Kettler ergometer FX1 (I am hoping that since you say it works with EX1, it will also work with my FX1). I bought an R Pi Zero WH. Great of you to have made this bridge, by the way ! :slight_smile: I have a question. I have gone through steps including the npm install, which I believe succeeded (lots of messages). BUT - how do I connect the Kettler AND the keyboard at the same time? It has only one USB port. Now, without bike connected and the keyboard connected, when I run “sudo node server.js” I get: “[KettlerUSB] port is not open, retry in 10s” looping until I Ctrl-break I assume that is because the bike is not connected? But if I connect the bike, how do I type in “sudo node server.js” since I will not have the keyboard connected (due to lack of a second USB)?

2 - second item is in a separate thread/issue

Thanks for any help and explanation!

Hello

I would suggest working headless on the raspberry pi zero. it means using a remote connection with another PC. start step 3 : https://desertbot.io/blog/headless-pi-zero-w-wifi-setup-windows

Or you can use a USB Hub, but I never tested this way.

Then using a remote connection, you will be able to connect the USB Cable directly to the Kettler. And KettlerUSB will try to open the serial port

Thanks a lot. In the meantime I managed to connect my Apple Bluetooth kbd (and mouse), over BT. So the USB is now free. When my SUB-RS232 cable arrives I will see if this works. If not, then headless (thanks for the link, it has a Mac version, luckily for me) is certainly a promising option.

Any chance on some help from you on my problem 2, which I wrote in the new Issue (Symlink not creating) I opened? Thanks in advance, much appreciated.

[thesoulpole]

Hello, Cable arrived, it seems to connect to the bike because bike screen displays a RS232 icon. However - it goes into a infinite loop - see attached photo any ideas on what to do? thanks in advance!

[360manu]

Good ! it works ! It' displays a log status that it receives from the bike the 25 on the line is your wattage

[360manu]

Now you should try connect it to Zwift or any FTMS BLE compatbile software (I saw a game on Google Play)

[thesoulpole]

Hey, you know what? It WORKS! ;)) I connected no problem!

Now I have to learn this Zwift (and see what actually works, and if there are any missing bits and if they are of interest)

Will let you know!
