Problem to Send data from HM10 BLE to Phone Application (Receiving is OK)

[Paul FREYER]

Hello,

I try to do a link between a HM10-BLE Bluetooth device and a PIC18F87J50.

I began to wrote an application with this BLE device and i successfully can send order to my PIC

in fact,it is not so easy as normal BlueTooth devices ..

I can only SEND String command from my phone to the Device

Connected

put  led On or OFF..

or disconnect 

but i can NOT receive on my phone,  some data trough BLE device  (data sended by my PIC..every 4 seconds.)

ie: i send status of 2 switches and an analog value.. collapsed in ascii (into a string)

B1=1;B2=1;E1=  199<CR><LF>

it seems that i don't use the correct UUID ?

i didn't find example on the web .

Please could you have a look on it

and give some advice to follow..

if necessary i can also join my MikroC program..

Best regards

hello,

i successfully find out the solution

maybe it was too much easy !

simply to use the event 

When bluetoorthLE1 Stringvaluechanged ..

i found another probleme with the slider

When i get the position , i get 2 times values .. why not only one ?

what i get into my PIC18F:

B1=1;B2=1;E1= 197 ;V1= 634            <- this is what i send to Smartphone
IT UART2 -> SL=156;SL=164;           <- this is what i get when changing position of slider
53.4C.3D.31.35.36.3B.53.4C.3D.31.36.34.3B.00.00.00.00.00.00.
B1=1;B2=1;E1= 196 ;V1= 631

Maybe you are reading from the UART less frequently that the AI2 slider changes?

In that case, there would be two writes from AI2, to the one read.

Situations like this are usually handled by including a delimiter like LF at the end of each message,

and specifying the delimiter value as an attribute in AI2 or as \n at the end of the text,

and programmatically in the micro vis commands like readln().

Hello ABG,

Thank's for this answer

I turned around this problem by using clock timer and Thumbenabled 

When i move the slider, it disappers one second and re appears just after moving the position

and so, i take only one slider value back to my PIC applicatiopn

B1=1;B2=1;E1=  141 ;V1= 454

B1=1;B2=1;E1=  203 ;V1= 654

IT UART2 -> SL=138;                              <- slider value 

B1=1;B2=1;E1=  213 ;V1= 686

IT UART2 -> SL=146;

B1=1;B2=1;E1=  203 ;V1= 654

IT UART2 -> SL=197;

B1=1;B2=1;E1=  201 ;V1= 647

B1=1;B2=1;E1=  210 ;V1= 676

IT UART2 -> SL=133;

B1=1;B2=1;E1=  205 ;V1= 660

IT UART2 -> SL=192;

B1=1;B2=1;E1=  203 ;V1= 654

IT UART2 -> SL=44;

B1=1;B2=1;E1=  212 ;V1= 683

A nice simple solution.

Thanks for telling us what worked.
