Hello, We have been trying to do acoustic ranger application with the micphone of the mts310CA sensorboard, we have three nodes: Node1: only sends an RF packet to node2 and buzz the sounder at the same time. Node2: Receives the RF packet sent from node1 and increments a counter (with a timer) until it detects the buzzer sound to calculate the distance between the two motes, then it will send a data packet to the baseStation node with the counter. BaseStation node (Node0): receives the data packet from node2 and displays the counter value. We are having a problem with node 2 when it detects the buzzer sound, the problem details are the following: The surronding noise can also trigger the MicSetting.toneDetected() event (mts310CA sensorboard), so we can't find the time when detect the buzzer sound. We don't know where the problem is exactly! We really appreciate your help and thank you in advance!
