I have a PR55-17A Wireless USB Modem and a PR55-61E 1-channel vibration sensor plus. The 2.4 GHz XBee3 stopped being read for some reason on the sensor; it cannot be detected on XCTU.
Swapped both the sensor and modem radios with the 900 MHz XBee PRO S3B. Downloaded the profiles and used XCTU to set it up. The modem is fine and is detected on Node-Red. However, the sensor is going into a blinking pattern as shown.
Is this the radio module that came with the sensor? At any point, was it taken out and connected to XCTU, and set to default or changed any other settings?
the led pattern indicates on board mcu cant communicate with the radio
The module that came with the sensor went through the same thing. So I took it out and tried to read it through XCTU which failed. Tried to troubleshoot following steps for no read XBee3s, which failed too. I had extra 900 MHz units lying around, and I have been trying to get the sensor and modem to work with them.
So no, these weren’t the ones that came with the sensor (the sensor and modem originally had 2.4 GHz ones). I can detect the modem one on XCTU but not the sensor one. I followed the instructions on this page.
and tried reconnecting, but this is what I get.
When I say I can detect, I can detect the 2.4 GHz modem but not the sensor one on XCTU. I can detect both the 900 MHz modules on XCTU.

The two profiles I used.
make sure your sensor xbee baudrate is set to 115200, i am suspecting its set to 9600
share all the radio settings
I do not have a reader for the radio module, so I have to swap the radios to the USB modem and read it through that. Hope that does not have any effect.
Modem Settings
are you using 900mhz or 2.4ghz radio in the sensor ?
900 mhz radio module in both
settings looks correct. while plugging the radio in the sensor make sure all pins are aligned properly.
Have tried that too. Can it be a hardware issue?
@Eduardo_Mtz please can you share instruction to update firmware. this is pr55-61 board
Hi @learningncdio please follow these instructions to perform firmware update.
Firmware Update PR55-61.pdf (3.6 MB)
Thanks.
I have followed the instructions. Now the wireless sensor does not provide any indication in the status light once reset is pressed (lights up when config is pressed). I have further reapplied both the profiles you have provided on the website and set the baud rate to be identical. and encryption off on both ends.
Hi @learningncdio Could you please download and install the Comm Operator serial tool from the following link:
This tool will allow us to monitor the log messages sent by the sensor. To proceed, connect the sensor to your computer using your USB Modem. Please note that the wiring for this connection is identical to the one used for performing a firmware update.
Once connected, please capture and share a screenshot of the logs displayed in the tool.
Thanks.
Is it fine to connect it via the USB serial adapter and not the modem? Once I opened the Comm operator, do you need a screenshot of it as it is, or do you want me to do anything?
P.S I have a message limit here; if that can be disabled, great!
