Hi,

we are using unmodified DSPS_6.150.4.50 with Pro Development Kit but we do not reach the performance which is mentioned in the UM-B-088 application note. Currently we reach about 17kbps (measured the beginning and ending of UART transmission). We have tested it with different devices and all need the same time to transfer the data.

Hi Firefox2005,

Thanks for your question. The DA14531 is acting as GAP peripheral, so it is running the sps_device project. But what about the Central device? Is it another DA14531, or a mobile phone?

If it is a mobile phone, what is the model and application that you are using?

The Table 11 refers to over-the-air performance, not from UART to UART.

Thanks, PM_Dialog

Hi,
 

we have tested it with a mobile phone. Huawei P30 Lite, P20 Pro and a Bluetooth Router.

 

@Performance, so how to do the same measurement as in the official document? There is no way written down to verify this.

We have a USB and Pro Dev Board which we can use for testing. Please explain how to do it.

 

Thank you!  :)

Hi Firefox2005

APologies for the delay. Would it be possible to send a sniffer trace over the air? What setup did you use to get the 17kbps throughput?

Regarding your question about the user manual, how we did the measurements, I have escalated internally.

Thanks, PM_Dialog

Hi Firefox2005,

As mentioned in my previous reply : 

1. Would it be possible to send a sniffer trace over the air?

2. What setup did you use to get the 17kbps throughput?

Thanks, PM_Dialog
