Welcome in the forum, Valery!
The CY8C4228xxx-BL chips have got 8 DMA channels. Use the Device selector on Creator to verify.
I can't find this P\N in device selector.
There is no even one BLE device that supports DMA in the device selector table. I'v filtered the table by DMA channels and BLE. the table shows nothing. what's going on?
I am using Creator 3.3 SP1. Can it be you are using a former version such as CP1?
I will update now :) thanks
