When I was using the device as peripheral, I was wondering when the Softdevice notified BLE_GAP_EVT_SEC_PARAMS_REQUEST and BLE_EVT_SEC_INFO_REQUEST:
1, when peripheral...
hi dear nordic employee:
I tried to build the project ble_app_hrs_c(pca10040) by keil5
but I get an error :

Hi,
I'm working on modification of DFU Bootloader to use external flash instead of standard Dual-bank or Single-bank version. Now it works quite well, but I have problems...
For programming the nrf52832's BLE capabilities the only option that can be used is the s132 soft device right?
According to the latest specification, the maximum throughput...
Greetings,
I have an application where the DFU of a NRF52 is performed by another microcontroller via a serial port. Once the DFU is complete, the microcontroller turns...
Hi everyone!
I'm wondering about why SoftDevice stays idle (in terms of radio operation) so "long"
("t ScanReserved" = 760 us) after channel changes during scanning? Despite...
Hi,
I'm trying to do a rough calculation of current consumption for the nRF52840 chip.
The unit should sample 6 times an hour by using I2C to acquire samples from a...
Hello,
I want to program the bare nRF52832 MCU over SWDIO, SWCLK, GND and +3,3V Connections with a Segger J-Link programmer. Unfortunately the programmer could not connect...
Hi,
We are designed our own Beacon PCB based on nRF51822 Beacon Kit...We followed board size,PCB Antenna Trace width and GND Clearance as per Beacon kit...The difference...
As I understand it only the largest physical chip, 7x7mm nrf52840 , supports Bluetooth 5.0 long range. Is this correct?
It seems as if Nordic Semiconductor is abandoning...
