Dear all,
hope you can help me.
I m using Node -Red for a while now on the raspberry pi 4. I updated yesterday to the latest stable version by using your update script.
My pi works in a **test bench and controls the measurements via a I2C-Bus connected AD1115** Converter. I am measuring pressure at 4 channels (single ended)
After a long search i recognized that my AD Converter does only react and run on deploy if it is copy then node again with same parameters on the same place and reconnected with all connected nodes that have been connected before.
I recognized to that the behavior at the first deploy is different than the behavior at the second deploy.
1. at the first deploy it disconnects and reconnects
2. at the second deploy it just connects.
I think that the error has something to do wit the restart.
My Questions:
- Can I generate a reconnect somehow (I2C reset?...)
- have you a different solution
The good thing is that the error is repeatable 😀
Thanks for your help in advance!
Clemens
