OTAP query: Device doesn't respond

Hello there,

I have setup OTA and I am trying to upload a new program for the first time

all commands seem to work however when I try to send a program

otap64 -send --file onehopdemo.cpp.hex --mode BROADCAST --deliveries 1 --pid prog001

C:\Users\xxxxxxx\Desktop\project workspace\Libelium\otap_0.1-b61\otap>java -Djava.
library.path=./lib64/ -jar otap.jar -send --file onehopdemo.cpp.hex --mode BROAD
CAST --deliveries 1 --pid prog001

this goes on for very long, I can see the progress for a second (and then it disappears) but it is VERY slow.. to make you understand the moment I am writing this message is it 54% done and has already done 2524 seconds

that is not normal, isn't it?

I tried also UNICAST, it doesn't make much difference

any advice?

cheers,
Spyros

I've uploaded a video on youtube on the operation of OTAP

http://www.youtube.com/watch?v=XdSMQwJAkjE

it's my first youtube video, I suggest you watch it in full-screen too and turn up your speakers :P

thanks my friend, this is very helpful!
I will do it again based on your video on the first chance and will let you know

even though I believe I did all these steps, my problem is that I get VEERY low speed on delivery of the program (which is mostly due to the many errors in transmission) and I don't know why... maybe it is just a small detail in the configuration that is why I will do it again!

cheers,
Spyros

Slow transmission under windows yes. but if you're using Ubuntu then the transmission is faster!

Thank you, I have managed to make it work with my 802.15.4 modules

But now I have ZigBee modules (Series 2) and it is giving me hard time again!
I scan and I get 0 nodes...

I have AP1 and BD=5
PAN ID is the same in both
channel: + ZB= not controlled. Chosen by the coordinator.
I suspect this could be a problem. So what should I set to the channel field in xbee.conf?
whatever I put it doesn't find any node

I used AmroQuandour's code from the video and it worked for me with XBee S1 but not with the S2 ones...

here is the code I uploaded to test OTA:

Code:

long previous = 0;  

void setup()
{
  xbeeZB.init(ZIGBEE,FREQ2_4G,NORMAL);
  xbeeZB.ON();
  xbeeZB.checkNewProgram();
  
  Utils.setLED(LED0, LED_ON);
  Utils.setLED(LED1, LED_ON);

}

void loop()
{
  previous=millis();
  while( (millis()-previous) < 60000 )
  {
    while( XBee.available() )
    {
      xbeeZB.treatData();
    }
  }
  
}

Try increasing the time for scanning.

Code:

./otap -scan_nodes --mode BROADCAST --time 6

it found it but I get the same problems

it gets until around 70% (with lots of no responds as always) and then I get this error

Delivery error: 74
Device doesn't respond
Device doesn't respond
Device doesn't respond
Device doesn't respond
Error sending packet
Error sending firmware
Node response: xPROGRAM RECEIVED ERROR

the command I used is
otap64 -send --mode UNICAST --mac 0013a200XXXXXX --file S:\ota\applet\otaconf.cpp.hex --pid prog000

is there anything wrong with the otap for 64-bit??

What's the size of the program you're trying to send?

AmroQuandour · **Posted:** Thu Jul 28, 2011 9:00 am

lefsp. Run it with a 32-bit OS. Use VMWARE and load a 32-bit Ubuntu OS on it and try it ... It's the only way to find out if there are any problems with the 64-bit version of it.!

I think I found what I was doing wrong, the API mode has to be 1 and I had it set to 2..
In general, this is not practical.. you say that XBee S2 modules need API mode 2 to operate, are we supposed to change API mode everytime we want to send firmware? won't this break the network?

the thing is that now I get flawless (and quite fast) transmission until 100% and then I get PROGRAM RECEIVED ERROR

I tried it several times..

I tried to upload the code you provided in the OTA documentation but I get a compile error:

Quote:

In function 'void loop()':
error: 'class WaspXBeeZB' has no member named 'checkOtapTimeout

so I have uploaded AmroQuandour's code as I posted couple of posts back.. this must work though as I have seen in the video he created..

in general, can you explain what is the minimun required code bits that a program must have to be able to receive and start a program OTA?
