Hi,

I'm trying to make a Java program to receive and send messages to micaz motes. In order to do that I'm using SerialForwarder and a mote programmed with TOSBase plugged on a MIB510. To test it, the motes are programmed one with CntToLedsAndRfm and other with RfmToLeds.

It seems to work when the mote sends me the message, because I can read it, but when the application tries to send a response (message with val=7 so the micaz must turn on the three leds), the mote does not respond and SerialForwarder displays the text "write failed".

I have also try the application BCastInject with a micaz with SimpleCmd and a micaz (in the MIB510) with TOSBase. I send the radio_louder (or other one) message and the micaz with SimpleCmd turns on the green led (so something has been sent through a Java Program-->SerialForwarder-->UART-->radio-->micaz) and SerialForwarder displays the text "write failed" again. Since this first message, no other can modify the state of the leds. Where is the problem?

I have seen similar problems in the mail list but I have not seen that they have been solved.

I'm sure you can help me. Thanks
