Configuring PR55-61N Using the Serial Port

Hopefully, this topic isn’t a repeat of another topic. I work for a company where we are trying to configure PR55-61N’s, and with the setup with the gateway we are using only allows one of us to configure at a time. I was wondering if it is possible to configure the sensor through the serial port using a UART Debugger. We’ve flashed the sensors with new firmware using the serial port, so we thought it might be possible to configure through the same port. Any assistance you could provide would be greatly appreciated.

The sensor can only be configured over wireless.
You can configure multiple sensors in one go by using the OTN feature and do not define any mac address in the sensor address section ( in node-red).
