JN5169 delay between sending of messages

Hi everyone,

I am using a JN5169 chip and I want to test the maximum data rate of the chip. In the IEEE 802.15.4 standard the maximum data rate is 250 kb/s. When I however test the data rate of the JN5169 chip, I get only a data rate of around 14 kb/s max. I noticed that there is always a delay of 3 to 5 ms between each message even if there are no other instructions between the calls.

I use the jn516x-Template as a code base and use the default parameters, can you tell me why the data rate is so low?

Hi Mario,

for the calculation i measured the time between to successful messages and then used the time to calculate the amount of packages which where theoretical sent per second. I multiplied then this value with the package size. For the measurement i used mean of the values from successful messages over the time of 10 seconds.

I haven't had a look at the document, thanks for linking it.

Hi Lucas,

I hope you are doing great.

How are you calculating the data rate?

Did you look at the Calculating 802-15-4 Data Rates application note?
