Hi Janos,
I tried the default RadioCountToLeds with cc2420x, with only the following
changes. Within 3 minutes, about 10% of nodes stop toggling led 2 and
crash. If MilliTimer fires every 100 ms, about 30% of nodes crash.
* event void MilliTimer.fired() {*
* counter++;*
* call Leds.led2Toggle();*
* ...*
*}*
* event message_t* Receive.receive(message_t* bufPtr, *
* void* payload, uint8_t len) {*
* dbg("RadioCountToLedsC", "Received packet of length %hhu.\n", len);*
* if (len != sizeof(radio_count_msg_t)) {return bufPtr;}*
* else {*
*// radio_count_msg_t* rcm = (radio_count_msg_t*)payload;*
*// if (rcm->counter & 0x1) {*
*// call Leds.led0On();*
*// }*
*// else {*
*// call Leds.led0Off();*
*// }*
*// if (rcm->counter & 0x2) {*
*// call Leds.led1On();*
*// }*
*// else {*
*// call Leds.led1Off();*
*// }*
*// if (rcm->counter & 0x4) {*
*// call Leds.led2On();*
*// }*
*// else {*
*// call Leds.led2Off();*
*// }*
* return bufPtr;*
* }*
* }*
Please let me know if you have any idea what may go wrong. Thanks for your
reply.
