Hi, I have the CC430F6137, I have been using "CC430x613x wake-on-radio Examples", the cuestion is what is the optimal configuration for the mode wor.
I have two cc430, one in mode WOR and the other if I press the button sends a packet, but the cc430 in mode WOR don't detect the packet unless i press the button several times times
I do not know the code example you are referring to but I can give you some general guidance as to how WOR mode should be used.
In a protocol where the transmitter does not send packets at a regular interval the receiver must wake up often enough to receive the required amount of preamble needed to be able to detect the sync word.
If the receiver needs for example 2 bytes of preamble to be able to detect a sync word, the transmitter could for example transmit 4 bytes of preamble for every packet. The wake-up interval on the receiver should then be equal to the duration of 2 bytes preamble to be able to detect the sync word. If the transmitter transmits 6 bytes of preamble, the wake-up interval should be max the duration of 4 bytes to be sure that the receiver will at least catch two of the preamble bytes.
The more power you can use on the transmitter, the more power you can save on your receiver. An alternative to sending longer preamble on the transmitter to increase the wake-up interval on the receiver is to transmit the packet multiple times on every button push. This will increase TX current but decrease RX current as the radio can sleep for longer periods.
The radio should be configured to terminate on RSSI so that if there are no signals on the air when waking up it will simply go back to SLEEP again instead of staying awake for the complete RX timeout period.
