Other Parts Discussed in Thread: TLV320AIC26

Hi, i made a circuit using TLV320AIC26 and CC1110 (reference from AN-082), it works fine with two way and one way sample code (swra295a).

Now i want to know how we can adress multiple slave in this. i don't want broadcast, i need communication between

Master - slave1,

master - slave2,

slave1 - slave 2

all i want 2-way, is it possible

    Hi Pradeesh, 

    That might be possible but note that the radio have is set up to use 250 kbps and based on the timing in the application note (Figure 3.) you will either need to reduce the audio quality further or increase the RF datarate to 500 kbps. You are not stating of all the audio communication is active at all times or if it is limited to between 2 devices. You will also need to look at the frequency hopping scheme as all devices need to be in sync with regards to frequency hopping. 

    The source code is available so feel free to do any modification you would like. 

    Best regards,

    Hi Kjetil,

    Thanks for the reply... yea all three devices ie; one master and 2 slaves will be active all the time, but if i need to communicate with slave1, slave2 should not receive thats what i want. any way i will do some excercises..
