Digi XBee 3 USB support #138

Closed oising closed 3 years ago

I just bought a Digi Xbee 3 USB key and unfortunately it doesn't seem to work:

@andreasfedermann -- I see you wrote the initial implementation. Is there anyway that I could help in order to fix this? Thank you!

are you sure the 115200 baud rate is correct (you can pass it as a command line parameter) ? I have a Digi XStick that works with the Playground app with a baud rate set to 9600

works from 1200bps to 961kbps according to https://media.digikey.com/pdf/Data%20Sheets/Digi%20International%20PDFs/Digi_XBee_3_USB_Adapter_7-17-19.pdf

tried with 9600 8n1

Flashed to latest zigbee 3 stack (which is emberznet 6.7.x) -- everything is fine in XCTU tool

So, I am reading the specifics of the AT command set for Xbee and I see that it's not in Command mode by default (it's in "Transparent" mode) -- you have to issue +++ on the line and wait 1 second for the OK to return before sending AT commands - such as a software reset FR (the point at where it's failing right now) -- I can't see anywhere offhand where you might be sending the +++ sequence -- is it possible that the Xbee model this was tested on is in Command mode by default?

Transparent operating mode Devices operate in this mode by default. The device acts as a serial line replacement when it is in Transparent operating mode. The device queues all UART data it receives through the DIN pin for RF transmission. When a device receives RF data, it sends the data out through the DOUT pin. You can set the configuration parameters using Command mode. https://www.digi.com/resources/documentation/Digidocs/90001506/Default.htm#concepts/c_mode_trans.htm?TocPath=Modes%257CSerial%2520modes%257C_____1

Ah, so switching the XBee3 into API mode (default is Transparent mode) allowed the playground to initialize... I also had the chip in coordinator mode and not router but I'm not sure if that is an issue. API mode works. I set the mode using XCTU tool.
