13.- HM-10 sends a long text to app.
p110_UNO_HM10_TextoLargo.aia (185.3 KB)
- HM-10 sends five random numbers with decimals, each random delay (500 - 1000 ms)
- It sends the data separated by commas and ends the message with the '#' character.

- App receives this information in packets of 20 characters in stringValues, for example:
(19.650,729.62,4154.3)(,584.019,279.315,#)
-
The total variable accumulates the information until it contains the character '#'
-
Cleans the information and makes it list.
19.650,729.62,4154.3,584.019,279.315, #
(19.650 729.62 4154.3 584.019 279.315 #)
(*)
Another way, send the last number using println()
BLE1.println(x5,3);
// BLE1.print(",");
// BLE1.print("#"); // End Of Message.
and modify the block piece: \n
