I am working on custom BitCloud software for an endpoint that will communicate with a SerialNet coordinator. Is this configuration supported?
So far, I am unable to get the endpoint to join the PAN. I have my PAN set the same. In SerialNet:
Code:
AT+WPANID?
+WPANID:AAAAAAAAAAAAAA10
On the endpoind, in Configuration:
Code:
CS_EXT_PANID = 0xAAAAAAAAAAAAAA10LL
I have the channel mask on the endpoint set to all 2.4ghz channels:
Code:
CS_CHANNEL_MASK = 0x7FFF800l
When the endpoint starts I never recieve a joined message on the SerialNet. I have tested the two physical devices, both running SerialNet, and they were able to communicate.
I copied the Makefile and Configuration file from the lowpower example. The code is a copy/paste mostly from the lowpower example and the user's guide. It is very basic, only currently intended to join the network. The code I used is:
Code:
#include <zdo.h>
#include <usart.h>
#define NWK_ADDR 10
#define NWK_UID 0x11AAAAAAAAAAAA10LL
#define APP_USART_TX_BUFFER_SIZE 500 // USART Tx buffer size
// USART Tx buffer
static uint8_t usartTxBuffer[APP_USART_TX_BUFFER_SIZE];
// USART descriptor (required by stack)
static HAL_UsartDescriptor_t usartDescriptor =
{
.tty = APP_USART_CHANNEL,
.mode = USART_MODE_ASYNC,
.baudrate = USART_BAUDRATE_38400,
.dataLength = USART_DATA8,
.parity = USART_PARITY_NONE,
.stopbits = USART_STOPBIT_1,
.rxBuffer = NULL,
.rxBufferLength = 0,
.txBuffer = usartTxBuffer,
.txBufferLength = APP_USART_TX_BUFFER_SIZE,
.rxCallback = NULL,
.txCallback = NULL,
.flowControl = USART_FLOW_CONTROL_NONE,

ZDO_StartNetworkReq(&zdoStartNetworkReq); // start network
sensorState = SENSOR_STATE_JOINING;
char msg[] = "NWKSTART";
HAL_WriteUsart (&usartDescriptor, msg, 8);
}
While debugging I get the "INIT" and "NWKSTART" messages as expected. I never get a "NWKConf".
I tried the code with all USART debug info commented out, mostly fearing HAL_WriteUsart() could not be called during a callback. It did not join the network.
I tried setting CS_UID_ID and CS_NWK_ADDR_ID both through the commented out code and through the Configuration file.
Anyone have any ideas? Is this configuration even supported by SerialNet, or must all nodes joining SerialNet also run SerialNet?
Thanks,
Mike |

Try to specify exact channel in CS_CHANNEL_MASK (on which coordinator is waiting).
First of all you need to find out why start confirm is never returned, this is not normal. Try starting coordinator instead of ED, is confirm returned?
Generally SerialNet must work with SerialNet, but they use regular ZigBee so at this point there should be no problems. |

I set the CS_CHANNEL_MASK on both to 20000, the device did not join the network.
I will try making the SerialNet node an end point and the BitCloud node the coordinator tomorrow.
I noted my WinAVR version is 20100110, but BitCloud's last release was on 11/09. Are they compatible? Is there a specific version of WinAVR I should be using?
Thanks agian,
Mike |

But confirm is returned? Until confirmation is returned it useless to try to join devices.

Generally it is not recommended to use different version of compiler. If nothing else will help try to change compiler version. |

I think I may not understand the terminology correctly. I am calling ZDO_StartNetworkReq(), and not getting the callback. The SerialNet coordinator does not send any messages that the device has joined the network. Wouldn't the confirmation be confirming the end point joined the network?
Which version of WinAVR matches the BitCloud SDK from 11/09?
Thanks again,
Mike |

This needs to be fixed first. Callback should be called anyway some time after request was called. Status field will show if node joined (or tell the reason for failure). This timeout may vary but should not exceed 15 seconds or so for channel mask with only one channel in it.
Post your code (complete, so I could compile it run here).

I switched to WinAVR-200913, which did not correct the issue.
I also tried switching the node to a coordinator, as you suggested. I have included my code below.
On the serial port I only received the "INIT" and "NWKSTART" messages, indicating the ZDO_StartNetworkReq() request was made. I let it run for a couple minutes and did not receive the expected "NWKJoin" or "NWKFail" messages indicating I received the ZDO_StartNetworkConf() callback.
I am very confused. How can a coordinator fail to start? My understanding is the coordinator is not dependent on any other nodes, so it should start regardless. Can you see any trouble with my code?
Thanks again,
Mike

Coordinator not failing to start, if it was callback would be called with error code. Something else is failing.
Code looks good. Attach complete code + Makefiles + everything that is needed to build application. |

I found a problem. That's my bad I did not remember that you not supposed to call stack functions in first APL_TaskHandler() invocation, it should be used only to set parameters. At least in current releases, it should work as expected in the near future.
To fix your code do following:
At the end of init():
Code:
sensorState = SENSOR_STATE_START_NETWORK;
SYS_PostTask(APL_TASK_ID);
And add SENSOR_STATE_START_NETWORK state in APL_TaskHandler() in which call startNetwork().
After doing so I've got:
Code:
INIT
Task
NWKSTART
Task
NWKJoin
