I have tried to use the IOT development board for DSPS device project , i am not getting any data in TERATERM window ?? , BLW scanner app detecting the device but DATA transmisson is not happening , what changes i have to make ??

Hi prasanth.velliyangiri,
Build the DSPS application for the 583 project and remove the HW flow control, those changes are sufficient in order for the DSPS to work with the IoT board.

i have tried #undef CFG_UART_HW_FLOW_CTRL ,
removing - #define GPIO_UART1_RTS_PORT GPIO_PORT_0
#define GPIO_UART1_RTS_PIN GPIO_PIN_3
#定义GPIO_UART1_CTS_PORT GPIO_PORT_0
#define GPIO_UART1_CTS_PIN GPIO_PIN_2 , seems still its not working , i downloaded the sps_device project in IOT sensor dev kit , DSPS app just detecting the device , no data on TERATERM ..Could you please help me with this issue ...thank you dialog team

Q1 : How to check my client device-DSPS host is working fine ??like checking sps_device via mobile app
Q2 :Either sps_device & sps_host is not working with IOT kit , i couldn't see any data in TERATERM
-I have disabled hw_flow_control - #undef CFG_UART_HW_FLOW_CTRL
-periph_setup.h. modified as following
P0.2 - UART1 CTS,
P1.1 - UART1 RTS (changed from P0.3)
P0.4 - UART1 TX
P1.3 UART1 RX (changed from P0.5)
- #define GPIO_UART2_RX_PIN GPIO_PIN_3 -> changed to GPIO_PIN_4
Could you please help me with this issues...Thank you...
Hi prasanth,
Since you have undefined the HW flow control you dont need an RTS or a CTS pin, also since you have disabled the HW flow control enable you must enable the SW flow control. Have you tried the steps i mentioned above ? Just undefine the HW and define the SW flow control and build the application for the 583 NOT the 580 which is the default. Also the IoT in order to print
data uses the Atmel processor, please try to use an FTDI chip on the UTX and RTX of the interface board to get the data properly. Leave the pins of the UART RX and TX as they are since those are connected to the UTX and RTX test points, the P1_3 isn't connected anywhere. Please check the IoT schematic. If you want to use the DSPS without flow control you will have to disable sleep.
Thanks MT_dialog

Could you suggest the specific FTDI chip which suits well with IOT Dialog BLE DEVELOPMENT BOARD..Thank you...
Hi prasanth,
I am using the TTL-232R-3V3 cable that uses the FT232R. You can also try to disable the sleep mode and use the Atmel processor in order to print data to your UART.
Thanks MT_dialog
