cc2541 BLE_Bridge

Hello

I try to send data using method SandDataToHost but i don't see any activity on TX pin (i have tested this pin as blink - the pin work). By this library i can read data from serial. May be my problem that i don't use CTS,RTS signals (I connect to my external MCU only TX&RX)? 

Does RTS/CTS signals reflect on transmission?

    Hi Denis,

    As noted on the Serial-to-BLE Bridge V 1.4.1 TI BLE wiki article, if you are using UART with power management enabled, then the MRDY/SRDY pins will be used. So, you will need to use the build configuration for no power management. Also, kindly configure your host MCU to not use RTS/CTS.

    Best wishes

    thanks for answer, but do you really think that power mode reflect on uart activities? i have wrote one-second loop that send some data SandDataToHost and can't to see any activities on terminal that connect to cc2541. Do i need to set UP (pull-up) any pin RTS/CTS to enable transmission? does state of RTS or CTS enable/disable activities of uart?
