    Good to hear.Maybe you have one of these cheap chinies copy of ESP SoCswhere GPIO4 and GPIO5 is wrong labeled .

    Hi Vasilis,no I did not yet.But I think this depends on how you are using your servo...It is very important that you avoid using long delays or loops with heavy stuff - because the ESP is not "realtime" and using internal interrupts for the WiFi stack.I had similar issues with servos in the past.My solution was not to nice, but working fine:- using a I2C multiplex PWM board - like this:http://www.aliexpress.com/item/Free-Shipping-16-Channel-12-bit-PWM-Servo-Driver-I2C-interface-PCA9685-for-arduino-or-Raspberry/32228349211.html?spm=2114.01010208.3.20.S0u7WE&ws_ab_test=searchweb201556_10,searchweb201602_2_10057_10056_10065_10037_10055_10054_301_10059_10033_10058_10032_10017_107_10060_10061_10052_414_10062_10053_10050_10051,searchweb201603_9&btsid=2874df8f-e32b-4657-8c88-...see more »Hi Vasilis,no I did not yet.But I think this depends on how you are using your servo...It is very important that you avoid using long delays or loops with heavy stuff - because the ESP is not "realtime" and using internal interrupts for the WiFi stack.I had similar issues with servos in the past.My solution was not to nice, but working fine:- using a I2C multiplex PWM board - like this:http://www.aliexpress.com/item/Free-Shipping-16-Channel-12-bit-PWM-Servo-Driver-I2C-interface-PCA9685-for-arduino-or-Raspberry/32228349211.html?spm=2114.01010208.3.20.S0u7WE&ws_ab_test=searchweb201556_10,searchweb201602_2_10057_10056_10065_10037_10055_10054_301_10059_10033_10058_10032_10017_107_10060_10061_10052_414_10062_10053_10050_10051,searchweb201603_9&btsid=2874df8f-e32b-4657-8c88-7a3924b5f506So please check first your code, if you have long delays or loops and try to avoid them.Or you have a board like that above - it should also work.Hope you can fix your issues.

    This is the reason I recommend the Arduino IDE 1.6.5everything newer did not work :(
