iOS may not, but changing iPhone version might make difference in data rate, especially if wifi interference is tested. Also the HCI iAP app is not optimized for throughput testing. The data is sent and received over uart, read/written from/to file, all causing lower values than actual chip can do. This is a sample app to show iAP and Spp functionality and not throughput.
Some test results:
Avg Payload throughput for iap2 app on 20719B1 board with WICED22.214.171.124 with WIFI activity as 215,779 bits/s.
Avg Payload throughput for iap2 app on 20719B1 board with WICED126.96.36.199 without WIFI activity as 459,720 bits/s.
Peer Used: iPhone 6S(10.3.2)
SheetalJ_96 Thanks for your reply!
Thanks for reminding, I may jump to this conclusion "iAP2 data rate related to iOS version" too quickly, it seems like I need to test more iPhone and compare the data rate result.
By the way, I used hci_iap2_spp for test because I plan to use HCI UART interface for transfer data to other MCU on our project.
Is WICED iap2 app sample should have higher data rate result?
What do you mean by 'WICED iap2 spp' sample, please elaborate.
In WICED 6.4 Make Target sample code "snip.bt.iap2-CYW920706WCDEVAL"
