ESP32-MINI-1 Single UART for firmware and AT?

[rob.shand@atsr.ie]

I'd just like to ask this, because it has implications for our layout:

It's been established that in PROGRAM mode, firmware is uploaded via pins TX/RX 36/35
The default assignments for the AT mode(for MINI-1 Bin) are TX/RX 22/19

Would it be possible to re-assign pins so that for AT mode, pins will be TX/RX 36/35 ?

You can view the datasheet of relevant modules. If these two pins have no special purpose, you can try to change the test. How to change the AT pin, please refer to this document: https://docs.espressif.com/projects/esp ... -port-pins
