Settings for ESP8266MOD ESP-12F QIO L4 #74

Open dontsovcmc opened 6 years ago

dontsovcmc commented 6 years ago

What should I choose for raw ESP8266MOD Ai-thinker ESP-12F QIO module? Chip ID: 0x00167881 flash_id: Manufacturer: e0 Device: 4016

Should I erase_flash by esptool for the first time?

Thanks a lot!

I have the same question - any one found a solution?

ivankravets commented 6 years ago

Could you program this board with Arduino IDE?

bevchou commented 6 years ago

I was able to get code to upload (just the blink sketch) using the Arduino IDE, but it is not able to run any of the code since it is stuck in a reset loop. I am not sure if this is caused by improper settings or if it is a hardware problem.

I lost several nights with the same problem on ESP-12-F QIO L4 and, finally, I discovered that it does not work in QIO mode but only in DIO mode! I have 4 of them, same batch from Aliexpress and all behave in the same way. In addition, I discovered that, should you read ADC, either via analogInput(A0) or ESP.getVcc() the radio section fails and WiFi is no longer available!

Radio section fails because you are reading too intensive without yield() in between. And yes, there is a tonns of esp-12-f marked as qio but dio actually. So ... just use dio mode.

Radio section fails because you are reading too intensive without No, it is enough one read and the radio fails forever. At lest, this is what happens on on 4 ESP12-F

here is a tonns of esp-12-f marked as qio but dio actually Of course we must use DIO or discard them. It is a matter of fact that it is a fraud to sell them as QIO. In addition, if they are DIO, I should have a couple of extra GPIO pins available for me, but this looks not true too.

Now there is a service to check modules: https://www.ai-thinker.com/service/autifake
