Hello,
I'm newbie in CC2540, HAL and OSAL development.
I've just understand callback and test a little code for using UART callback :
When callback triggered, I read a byte with UART_RX and send it just after with UART_TX @115200bauds.
This test is OK, but there is a problem : the delay between RX and TX char is about 6,3ms (My final prototype will need to follow 5bytes @512Samples/s, so with actual delay, I will lost a lot of packets...).
I've tried a lot things to reduce this delay (UART config parameter, HAL_UART_DMA instead of ISR, stop cb_task (cbTMP112, cbLIS, cbBLS and cbDEMO), stop POWER_SAVING) but delay is always the same (except in DMA mode : about 7,4ms).
Have you an explanation?
Best regards,
Hubert
