sahniana WROTE:this is a transceiver module.
1. is it possible to have, for example, 3 transmitter 1 receiver (total 4 module)?
2. is it possible to have 4 module to communicate with each module that it want? all in transceiver mode. for example, i have 4 module. 1 want to send data to 2, 2 want to send data to 4, 4 want to send data to 1. is it possible using this transceiver module?
1. Is possible, but bear in mind, it is a transceiver, you cannot force one to be transmitter only. Say you have 3 modules that will transmit data only, 1 will be receiving only. Let's label it as T1, T2 and T3 for transmitter, R1 for receiver. When T1 transmits, T1, T2 and R1 will receiver the data if they are within range and same channel (since you want all 3 transmitter's data to be receive by R1, they must be in same channel), same goes to when T2 and T3 transmit. If T1, T2, T3 does not care about what is being receive, fine! You will get your system up where R1 will receive data from all 3 transmitters, but there is about problem. What if T1 and T2 transmit data at the same time? It will interfere with each other and corrupt the data which should be received by R1. Is there a way to make sure all 3 transmitters do not transmit at the same time?
2. Again, goes back to the 1st setup. All transceiver will receive the data send out because there are in same channel.
