Thanks, work properly!!! I found some additional info about HC-05 http://www.buildlog.net/blog/2017/10/using-the-hc-05-bluetooth-module/ note: 1) to know the default variable add "?" Ex: AT+NAME? otherwise you will get ERROR[0] 2) lowercase "at" not worked for me 3) AT+VERSION was v4 4) AT+POLAR return ERROR (but without this setting it work normal. In this link you can get a bit info about this settings (http://www.buildlog.net/blog/2017/10/using-the-hc-05-bluetooth-module/) 5) after AT+ORGL it restarted and you need to reconnect and change HC-05 mode 6) to change MODE need plug on power, than press reset button and keep hold it, then plug on power, LED would blink 1 times to 2 second

have somebody resolve this issue?

@Clarice Lang All fine, just do this for all servo (c* *) ex. C8 5.. 8 is number of servo next number ( 5 ) is angle.. you need use number for angle from 5 (-5 you can usue too) that press ’s’.. next step download main programm
