Re: Cannot connect to ESP8266 in AP mode with Android
Posted: Wed Jun 10, 2015 9:18 pmMy problem has been resolved with the release of SDK version 1.1.1.
This latest SDK version does introduces a problem that produces linker failures when attempting to compile the IoT_Demo included as an example App with the SDK.
But here is how to fix the error when compiling/linking:
The problem is that the "Makefile" does not include the pwm library. This must have been part of a different library with prior SDK versions. The updated "Makefile" entry should be:
Also, if your project is based on an earlier version of the SDK, the following function needs to be added to user_main.c just before the user_init(void) function:
You can look at the programming manual to decide what option to set, I selected "2"
defined as "No radio calibration after deep-sleep wake up"
With SDK 1.1.1 and the tweaks noted above, I can now connect to the ESP8266 in AP mode from my Android phone.
PROBLEM SOLVED!
