My NRF52811 Custome board not working as my application.

[mandha_amarr]

Hello,

1) I am using the PCA10040 to program a nrf52811 chip on a custom board with SDK 15.3.0.

2) I'm using the example ble_app_uart_pca10040_s112 on uKeilV5

3) Initially i tried to flash Softdevice and application using nRFgo Studio,

but when i connect my board with PCA10040's P20 connector, and nRFgo studio showing "recover" and "enable reset pin" boxes.

4) Then I am following the steps in Infocenter

https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.3.0%2Fgetting_started_installing.html

https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.3.0%2Fgetting_started_installing.html

for flashing SD and application code and it showing below attached text of JLInk segger.

ISSUE:-
-------

1) As per "ble_app_uart_pca10040_s112" code LED_4(P0.20) should blink with delay of 1second but it is not working lke that but some extra port0 pins are showing high.

2) Actually my aim is to use custom board (NRF52811 SoC) for advertising ble and use mobile bluetooth app for communicating it(custom board)

for my application which softdevice should i use? S112 or S140 for NRF52811?

3) I read some where S112 won't support Codec PHY?

So please can anyone help me to come out of this problem.

Thank you in advance,

Rgds,

HI,

YOu can refer to the example on https://github.com/NordicPlayground/nRF52-ADC-examples/tree/master/ble_app_uart__saadc_timer_driven__scan_mode.

Hi jimmy Wong,

Thank you for response, I downloaded that code which you given link and then i run it. It is running and giving Four channel 

ADC data. Like below 

ADC event number: 0
ADC Value 348
ADC Value 695
ADC Value 347
ADC Value 695
ADC event number: 1
ADC Value 348
ADC Value 696
ADC Value 348
ADC Value 695

But it is running once only after pressing  reset button. it is not running continuously .

I want to read the ADC values continuously with some delay, Is it possible to do that in your suggested code.

Thank you.
