Hello :),

I need

help

to solve the

communication between processor

C805

and

BL module.

Devices communicate

via

UART

(serial

port -

>

TX

/

RX

pins

)

and I need

to do a basic

setup

.

Then

send

it

AT

commnads 

BL

module

.

UART

is working

well

,

and

after turn on

BL

module

get an answer

 

AT

-AB

-CommandMode-

AT

-AB

BDAddress

BDR

But

when I send

some

AT

commands

are

unanswered.

I do not understand

the syntax

is respected

.. just

do not know

whether

statements end with

\

r

\

n

or

something

like that.

Or whether they are

poorly

chosen

AT

commands

in the communication.

Please help me :) guys, tnx

This isn't an 8051 forum, or one for this module. If the module is non-responsive you'd perhaps want to check the power, and signalling via a scope. That you've got the Tx/Rx sense right, and the baud rate and framing correct. If you are unfamiliar with functionality try connecting it to a PC first, use terminal applications there and then go embedded when you have more insight.
