I am using node-red mobile via a termux, I am trying to connect a RFD 868 module to mobile and receive serial data through it via a USBA port. I have connected a USB type C docking station with mobile which have three USB A port.
When I connect the docking station it shows three ports and I have granted access to the ports too via termux api. But when I try to use the port on Nod-red I receive the following message
[error] [serialconfig:29f6efabb67db2b8] serial port /dev/bus/usb/001/003 error: Error: Error: Permission denied, cannot open /dev/bus/usb/001/003
Through same setup on the same port via "free USB serial" app I can receive serial data successfully. But on node-red mobile app its not working. Node red don't ask to select USB port it automatically denied the permission.
