4 years ago No, you cannot use these pins. The firmware for CC2531 does not include a UART part. The firmware for CC2530 will not work on CC2531.

4 years ago @ptvoinfo your statement contradicts my hands-on experience.
I flashed CC2530_DEFAULT_20190608 coordinator firmware onto a CC2531 and was able to communicate with it via serial over the P0.2/P0.3 pins. I paired and talked to an end device, which worked too. (Tested with Tasmota 8.2.0 and an Ebyte CC2531 dongle. I only tried powering it through the Vcc/GND pins, not via USB.)
My answer to @dewi-ny-je is: Yes, flash the CC2530 firmware to CC2531, then wire it up as a CC2530, ignoring USB completely.
The fact that CC2530 (coordinator) firmware works on CC2531 doesn't feel like a coincidence, though I haven't read through the source code or datasheets. Either way, should this fact be mentioned e.g. in the coordinator README?
Edits: Just typos.

3 years ago @rudo-thomas can you update the wiki/website pages, in particular https://www.zigbee2mqtt.io/information/supported_adapters.html and https://www.zigbee2mqtt.io/information/connecting_cc2530.html to mention that the CC2531 works too?
Honestly I tried to understand where the source for the website is stored, but I couldn't find it.

I have a CC2531 connected to my server. I found that, even using the provided external antenna, the reach is not enough and I would like to relocate the device.
I have another spot very suitable, but without any server nearby. I thought about using the es8266 as described in the website in association with CC2530.
Can I use the same procedure with CC2531? The debug interface does not provide serial in/out, but there is a row of unpopulated contacts, the first two (p0.2, p0.3) apparently the same used in CC2530 to provide the serial tx/rx.
I can solder pins there and check, but is the firmware for CC2530 and CC2531 identical? Or should I reflash it? I'm currently using zstack 1.2 coordinator, default.
If you provide me with sufficient details so that I can test it, I will report the results and edit the wiki page accordingly with all the steps needed.
