@fiwi:
If you flash this firmware correctly you can no longer talk to it through the serial lines, as they are communicating with your COM port wirelessly. That is what the "transparent bridge" means. Instead of the USB wire, you talk to it over wifi.
The way to talk to it now, and send +++AT commands, is using TELNET.

I use this Software to send +++AT commands via TCP: https://packetsender.com/
Its very easy to use and able to store macros.

I get that, but the problem is it no longer connects wirelessly to my router after flashing the bridge firmware, so I can't telnet to it either.

It connects via WiFi just fine with the "AT 0.9.x.x" firmware, but as soon as I flash this, it no longer connects to my router.

Maybe I'm missing a step I need to do?

I have had difficulties with one firmware programming software, can't remember which. I am now using the NodeMCU programmer (the black one) and never had problems with it.
