I was right the first time.
You see, I don't keep it in my head all the time, and frankly I'm getting tired of looking it up for everyone. That's why I referred you to a schematic and proposed to think a bit for yourself. |

i understand that You are frustrated, but it's my beginning in zigbee.
Now I find in datasheet that's pins 38 and 39 are for USART and SPI. |

| I don't know what works with stk200, I'd try avrdude or avarice. |

Hello everyone ,
I am new to AVR RAVEN and I am working on a project with two modules without RZUSBSTICK.
My goal is to write a simple program that allows wireless communication between this modules.
I already seen the documentation but I cannot found what i want.
Can anyone give me a hand?
Thanks everyone. |

| Use "6.7.8 +IPR - Serial port communication rate" command. It is described in the datasheet. Keep in mind that changing baudrate will result in increased baudrate setting error. |

| Check that your PC is set to 1200. Then if you don't have oscilloscope there is nothing you can do but reprogram the module. |

| Probably there is too much difference between sending and receiving side. You can't set exactly 1200 using 8 MHz crystal. |

Hi all,
Is the current firmware that uses SerialNet and AT commands available as a source code and is it possible just to upgrade that code with my own routines? I plan to use UART bootloader, but which compiler should I use in that case because I am new with Atmel (have used another MCUs).
Second question is about modules themselves: Does the coordinator command to router/node wakes up the router/node if it is in a sleep mode, or the router/node processes command after it wakes up by previously defined scheme?
Thanks ahead!
BR,
Sergei |

No, SerialNet source code is not available.
Radio is turned off in a sleep mode (hence "sleep"), so the only way to wakeup is using external interrupt or timer. |

Thank you very much alexru for your quick response!
Is the PeerToPeer source code similar to default one in the module's MCU and if not, what are basic differences, in short?
Are there any limitations in default firmware concerning number of nodes in network like in P2P example?
BR,
Sergei |

| There is no default PeerToPeer in the module. By default modules come only with serial bootloader. |
