CC3220MODA: replacing cable 1mbit , latency question

Colombo Carlo

Part Number: CC3220MODA

Hi everybody ,

I would like to replace a serial connection via cable with a radio link .

I just need half duplex communication and distance to cover is max 3-5 meters .

the throughput is 1mbit/S ( so 100 bits every 100uS ) , what I need is the 100bit must be received on the other side before a new frame comes in : i must guarantee 100bits every 100uS max . this is mandatory

do you think this is feasible ?

should I use std wifi or I must go for some RAW data ?

will using 5GHz ( a different module ) make life easier ?

any input is welcome

regards

Hi Carlo,

Our device supports up to 16Mbps on UDP socket and 13Mbps on TCP so it shouldn't be a problem. Customer should test this given performance may vary by environment, network overhead and equipment being used.

Hi Jesu ,
but could you mantain a continous flow @ 16 or 13Mbps ? is it allowed ?
please which examples you reccomend to use on launchpads to run a test and show this ?
better UDP or TCP for my app ?
thank you very much
best regards

Hi Carlo,

I believe network terminal allows you to create a socket through the command interface and send an N number of packets. I do not know which is better for you - TCP has more overhead but is also more reliable. You know application better than I do.

Hi Jesu ,
do you know any example for a continuos data flow ?

Hi Carlo,

Try modifying the power_measurement example to send packets indefinitely. In power_measure.c you'll find various while loops with sl_Send commands in them. I believe you can just make those while(1) for whatever power mode you're using. Make sure you keep track of the type of socket you're using. This examples uses multiple depending on setting.
