- Wed Feb 17, 2016 5:10 am #41274 I'm new to ESP8266, but an experienced hardware/software engineer. I've recently received my first NodeMCU - a 32Mbit board from AliExpress.... plugged in and it appeared to work fine after some fiddling to find the right baud rate for PuTTY. The board came with AI-Thinker firmware, my phone could see the Wifi, so I thought... let's go straight for the node software.

I flashed the latest integer build and found that I got the boot message but not the user prompt and no wifi detected by my phone. Hmm.. must be a problem with the way I flashed it, I thought, so let's go back to the AT software. I've tried both the AI-Thinker code and the Espressif code with the same results - it flashes fine. I can issue and get responses to AT commands, but my phone doesn't see the wifi. The CWSAP command confirms the SSID is not hidden, so either the radio is faulty or there's a wrinkle to flashing that I haven't sussed out yet.

Any pointers welcome!
Thanks.

In desperation, I tried the espressif 1.5 boot code again and it sprang into life. Wish I knew what the problem was but at least I know the hardware is good. Now I just have to get a working nodemcu install.
