Agree completely!

Yes, of course! Especially in BLE.

Ok.
How to do this?
For example, how to tie uart1-tx function to GPIO5 ?
Which register is responcible for that?
Which number I should write to the register?
Is there macros for this purpose?

SD_DATA3/SPIWP/GPIO10/HS1_DATA3/U1TXD pin is used for external SPI Flash in ESP-WROOM-03 module.
So there is no possibility to use the pin as uart U1TXD.
Is it possible to confugure UART1 to any GPIO, as mentioned in ESP-WROOM-03_Specifications ?
How to do it?

I don't think that threre is ESP32 inside. See http://www.pycom.io/solutions/py-boards/wipy/

me-no-dev wrote:@windalser here is the "fix". It really did not delete the binaries from previous builds so they grew in size.

Yes, it works much faster now, thanks!

About slow aploading. I think there are something unlogical in uploading. Size of eagle.app.v7.irom1text.bin is 11572 bytes but script uploads 306176 bytes. Size of eagle.app.v7.irom0text.bin is 217985 bytes but script uloads 577536 bytes. It takes a lot of time and ineffective uses resource of flas...

I've compiled and upload IoTmanager4.ino (https://gist.github.com/4refr0nt/d2cb23626bd6c7ebb8a0 ) for ESP32 with the newest Arduino. It connects to wifi AP but crashes on connetction with MQTT server.. ... ю ets Jul 5 2015,rst cause:12, boot mode:(13) _stack_sentry: 0x3fffe1d0, __stack: 0x40000000, ...

I have not looked at UDK's upload script, but you can change the bandwidth and upload faster ;) Yes, I know ;) I tried to compile IoTmanager4.ino ( https://gist.github.com/4refr0nt/d2cb23626bd6c7ebb8a0 ) for ESP32.

Well done! Thanks a lot!
Now it works.
I have already installed new Arduino IDE 1.6.7 from .zip file to the С:\ directory.
Then I renew your code.
See attachment.
Uploading takes quit a lot of time compared to UDK (Unofficial Development Kit) ...
