As we know, now the zigebee binding works with TI2531 dongle which is also a evaluation board for the cc2531 chipset.
However, for this TI2531 evaluation dongle, the original firmware is
NOT what we need. we need to program another firmware from TI website.
However, except this TI2531 evaluation board dongle, is that any
other commercial product, like a usb dongle, which also use this TI2531
There are a number of these boards available if you search the web although there aren’t too many nicely packaged products. I know that the PINE64 guys have one as well but I don’t think it’s available yet.

I am not sure I understand you correctly. Basically my concern is,
Within the boards available which use TI cc2531 chipset, does some board already have the firmware pre-programmed which can work with zigbee binding?
I do not know of any that have the right firmware and are currently available. I know pine have one but I don’t think it’s available.
