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...
