I have been trying to compile and run UARTIO application of CSR. I can see " Last sleep state: warm_powerup" and "Type something" on PUTTY terminal. But I do not see anything on PUTTY when I type a word (Hello world). How to run this example application?

Can I access the application note of uartio application?

Try to connect USB UART TX to RX (with no PCB link) and see if you got echo anything you type on PC. 

If above OK, test boud-rate in CER1010 and on Putty

Did you solder the TX/RX point on CSR demo  PCB ?  see https://goo.gl/1IvSXk

1. Try to connect USB UART TX to RX (with no PCB link) and see if you got echo anything you type on PC. 

Yes I can see the output

2. If above OK, test boud-rate in CER1010 and on Putty

I used following configuration and set it to putty
/* Enable UART 115200*/
  UartConfig(0x01d9, 0x00); 
 

2. Did you solder the TX/RX point on CSR demo  PCB ? 

Yes I did

Are there any suggestions to solve this?

Is CSR1010 TX is connect to UART RX ? 

and CSR RX to UART TX ? 

Is UART 3V and NOT 5 V ? 

 

If nothing helps, call my Skype nissim.test
