- Mon Nov 07, 2016 4:30 pm #57794 I am just starting with two ESP01 boards from ebay. They were working fine before flashing nodemcu, and even few commands after the flash. I think they both stopped responding after I issued get IP command from lua loader 0.91. Now I can still reflash them successfully, but they do not respond to any command over serial, no matter what I do. I have them connected over FTDI1232 programmer.

I added separate 3.3V ps to no avail. Any help appreciated!

I had same issue of non-responsive ESP-01 after flashing Nodemcu FW before I flashed 1MB ESP-01 module with latest Modemcu FW along with "esp_init_data_default.bin". I tried this procedure on 2 ESP-01 modules and both work as expected.
