Before sending text, you must first test (if/then) to insure you are Connected.
If not connected, don't send.
Also, what is servol in your sketch?
You will get better answers if you upload the entire text of the sketch and an exported .aia file in addition to downloaded blocks images.
You don't show all the blocks. The problem is with blocks sending data to arduino.
this is all my blocks
Should i write more?
Please help...
