Forum Post: RE: UART communication problems with cc2541 and BLE stack 1.2.1

Hi GregS,

I have compared the _hal_uart_dma.c file between the archive you referenced and the one present in BLE-1.3 release and there are many changes. Would it be possible to port the power management change to the BLE-1.3 base and update the archive on the wiki?

Thanks!
