    Default Bought this RF modules

    hello
    http://www.dx.com/pt/p/rf1100-232-cc...Q#.VbtNY_NViko

    Bought this RF modules is working there are times that he forgets the configurations have to connect the PC to reconfigure all
    how could I send the configuration to it when I connect the PIC
    The modules are configured in hexdecimal
    Elguem have an idea how I do it or somebody already had this problem.
    RF1100-232 command table

    Set serial port baud rate

    Text Command Code Baud Rate Description
    Length 2 bytes 1 byte 0x01: 4800
    Format hex hex 0x02: 9600
    Fixed 0xA3, 0x3A 0x01/0x02/0x03 0x03: 19200





    Example: sending 0xA3, 0x3A, 0x03 to the module sets the serial port baud rate to 19200.

    Set channel communication rate (not supported/implemented according to the documents I found)

    Text Command Code Channel Rate
    Description
    Length 2 bytes 1 byte
    Format hex hex
    Fixed 0xA5, 0x5A 0x64






    Set channel

    Text Command Code Channel Number
    Description
    Length 2 bytes 1 byte Channel number from
    Format hex hex 0x00 - 0xFF
    Fixed 0xA7, 0x7A 0x00-0xFF (256 channels)





    Example: sending 0xA7, 0x7A, 0x10 to the module sets the channel to 16 (0x10 hex).

    Set module ID

    Text Command Code Module ID
    Description
    Length 2 bytes 2 bytes 2 bytes module ID
    Format hex hex 0x0000 to 0xFFFF
    Fixed 0xA9, 0x9A 0xFF, 0xFF






    Example: sending 0xA9, 0x9A, 0x00, 0xFF to the module sets the module ID to 255 (0x00FF hex).

    Set TX power

    Text Command Code TX Power
    Description
    Length 2 bytes 1 byte transmit power (dbm)
    Format hex hex 0x00, 0x05, 0x07
    Fixed 0xAB, 0xBA 0x00/0x05/0x07/0x0A
    or 0x0A (10 decimal)





    Example: sending 0xAB, 0xBA, 0x0A to the module sets the TX power to 10dbm.

    Read config from module

    Text Command Code Returned Data Format
    Length 2 bytes 1 byte 1 byte
    1 byte 1 byte 1 byte 2 bytes
    Format hex hex hex
    hex hex hex hex
    Fixed 0xA6, 0x6A 0xA6
    Channel
    Channel Rate Baud rate Power Module ID




    Example: sending 0xA6, 0x6A to the module returns the following data containing the module's current config:

    0xA6, 0x10, 0x64, 0x03, 0x0A, 0x00, 0xFF

    0xA6 - start of config dump (fixed)
    0x10 - Channel number 16 (0x10 hex)
    0x64 - Channel rate (fixed)
    0x03 - 19200 baud
    0x0A - 10 dbm TX Power
    0x00, 0xFF - 2 byte module ID

    Hi Cesar;

    Yep, the configuration sometimes disapears from those RF module. I really recommend the HC-12. They are cheaper than those, and works better.
    By the way, are you brazilian or portuguese?
    Thanks and Regards;

    I'm having such issues with NRF24L01+ .. Especially when this RF chip , and an inductive load are on the same circuit .. I have solved this issue by adding a transistor design to the circuit for only a purpose of switching it off , switching it on and reconfiguring the registers on certain periods in each loop ...
    Perhaps that may help you too ..

    Yes, those modules suck!

    Sim, esses módulos não valem nada, falham muito. Experimenta os que eu te disse, os HC-12. Comprei uns poucos e funcionam muito bem, e são mais baratos.
    Ou então os NRF. Mas para trabalhar os HC-12 são melhores porque é UART puro, enquanto que os NRF não!
    Thanks and Regards;
