Sonoff ZBDongle-E communication error change states ONLINE - OFFLINE

1

Hello,

I am running OpenHAB 4.2.0 on a Raspberry Pi Model 3 B Rev 1.2 1Gb.

I have just plugged in a Sonoff ZBDongle-E as my Zigbee coordinator. It is running firmware 6.10.3.0

It initialises fine, comes online but eventually goes offline due to a communication error. I haven’t configured any channels. I only have the dongle connected, and no other Zigbee devices yet.

Setup and error below.

I’m not sure what I am missing, and hope someone can help.

Cheers.

Hi check your setting
Based on what you posted you have flow control set incorrectly
refer to this documentation and confirm you have it all configured as specified.

Serial port Configuration

If you are using a config file, the serial port needs to be configured as shown in the above example. Below is a list of the relevat settings concerning the serial port.

Setting Allowed values
zigbee_baud Ember controllers: 38400, 57600, 115200
Telegesis controllers: 19200, 38400, 57600, 115200
Xbee controllers: 9600, 57600, 115200
CC2531 controllers: 38400, 57600, 115200
zigbee_flowcontrol 0 = None,
1 = Hardware (CTS/RTS),
2 = Software (XOn/XOff)
zigbee_port The name of the serial port, e.g. /dev/ttyUSB1 or /dev/ttyZigbee or whatever the port is named on your system

Hi,

I have tried the correct settings and it never comes online. If I turn off flow control, OpenHAB reads the Zigbee mac address and firmware version and comes online, and then of and on again until it’s permanently offline. If I use the correct settings, it never comes online. Using no flow control, and then getting it online and adding the correct settings makes it go offline immediately.

I have just received the latest dongle from Sonoff so will look into this soon. Unfortunately I’m travelling abroad from Monday so it might become a “hotel task” for late next week or the following week… I can confirm though that it communicates fine within the standalone console that the zigbee binding uses for testing, and stays online, but that’s as far as I’ve got with testing this.
