Hi,
I'am having an issue with UART using app_uart_fifo.c (SDK 0.9.2). At times I get communication error (usually at attaching and detaching uart connector) and my error...
Hi.
I'm little worried about our bt sensor power consumption.
We are using twi/i2c to communicate with sensors periodically. We are using app timer to trigger these...
I have a custom board that doesn't use the external 32Khz crystal. The engineer that designed it chose to use P0.0 as UART RX. (I know, poor choice.) I have set up a custom_board...
I am using SDK_11 s130. I see APP_ERROR_CHECK(err_code) being used throughout the SDK examples. When err_code is any value other than NRF_SUCCESS, the nRF51-dk board will...
Previously, I was able to program ble_app_uart using SDK_11 s130 into nRF51-dk. Now, I would like to program ble_app_uart into Adafruit Bluefruit LE friend board. www.adafruit...
I have been following the advertising tutorial and decided to start my own application using nordics git repo as a reference. After a few debug sessions I found that I needed...
I am trying to probe sysclk signal on one of the unused GPIO pins on a nRF52 board. I modified the ble_app_template example provided in SDK 11.0.0 and added a sysclk function...
I am trying to connect nRF52 with 7120 and create a NFC card reader , is this a solution and power efficient solution .
I will interface through I2C , is there a example...

Hi, If I understand correctly the debugger on PCA10040 can operate in 6MHz/n as SWO frequency.
the nrf52 can operate at 4,8,16,32MHz swo frequency.
How are we to use SWO...
I am using SDK_11 s130 on nrf51-dk. When err_code is any value other than NRF_SUCCESS, APP_ERROR_CHECK(err_code) will cause nRF51-dk board to reset. How can one get APP_ERROR_CHECK...
