Is ... (more)
Hi, I beginning now to program nrf51822. I would like to let the nrf51822 wake up after 3 hours by using a software timer interrupt. Should I use power_manage()? Before each power_manage() call, I stop all timer running. Current consumption ... (more)
I'm currently designing a board with nRF52840 and I'd like to use an antenna that is a DC short to ground. Do I need a DC blocking capacitor in such configuration or is it ok to connect ... (more)
hi, Is there any working PDM example for nRF52832? or can anyone give a sample initialization code for PDM with easyDMA using the inbuilt nrf_pdm_drv functions?
I am developing an application which involves control of a brushed DC motor with a quadrature encoder. According to this post, in SDK 12.2.0 - which I am using - it is possible to set the sample period to 128 ... (more)
Hi, I am trying test nRF52840-pdk throughput.

With calls to these functions: nrf_drv_gpiote_init() nrf_drv_gpiote_in_init() nrf_drv_gpiote_in_event_enable() I have a handler (interrupt) routine that services a CAN bus chip on SPI bus. The handler runs when the chip's interrupt output, connected to a nRF52 GPIO input, goes from ... (more)
For an application I have a nRF51 at my disposal and I need to transfer about 3'000Bytes. I found in the documentation that the nRF51 can use the S130 SoftDevice which support BLE 4.2. The data I ... (more)
May I know, How to flash the firmware for ATSAM4 which is used for flashing and debugging nRF52840. And also how to get the firmware?
I am using an Android application to send data to a nRF52 board. The nRF52 board is the peripheral and the Android phone is the central. This is the link establishment process:
I just test nRF52840 DK with ble_app_att_mtu_throughput_pca10040_s132 example. I know BOARD_TESTER transmits 1024 dummy kbytes to BOARD_DUMMY. I want to replace dummy byte by my data. How can I do this? Thanks for your help!!!
I'm migrating from SDK11 to SDK13. My custom service is based off Heart Rate Service, so I started from the new SDK13 example of HRS, and updated all the initialization code following the new example.
Changed: ble_cg.common_cg.vs_uuid__cfg ... (more)
