It is good practice to prefix the includes from one's C libraries with a directory so that they are all part of the same 'include namespace'. Unfortunately the Nordic SDK...
Hi, is there an available developer in my tri-state area of Minnesota, N. Dakota, or S. Dakota? Please call me if you are available for a project for hire. The developer should...
I'm trying to design a very low power sensor that takes readings using ADC and SPI 200 times a second. I'm a bit worried by the current EasyDMA uses (1.1mA). As far as I can...
Hi, I am working on a project where I want to make one nrf51288 chip as central hub and connect that to a android phone and other salve nrf51288 .

Hi,
I have a code programming the nRF51422 development board to write to a Sharp Memory 96x96 pixel LCD screen using SPI.
Currently the code writes two numbers and a...
Hi!
I'd like to collect statistics from BLE physical layer, namely about errors that have occurred in receiving packets on a BLE advertisement channel. I see from custom...
Hello, I working on nRF52DK, for programming am using Eclipse IDE. For that I am following nordic tutorials here
I need to add a new project it does't have any makefile...
Hello dear Engineers!
the questions are should I connect pins DEC2:A18 and DEC2:E24 externally ?
shuold I use Capacitors to decouple both these pins (in Reference no...
Dear developers,
we are considering purchase of a reliable programmer capable to flash the nRF51822 in production, one possible option is the SEGEGR FLASHER PORTABLE or...
Hi!
I have noticed strange problem with one of GPIOs - P0.15. We have tested 50 devices based on nRF52832 and 3 of them have problem with P0.15 after few days.
P0.15...
The default I2C address of my sensor is 0x29 (7-bit).
If the least significant bit is low (0x52) the message is a master write to the slave. If the lsb is set (0x53) then...
I'm using SDK 12.2.0 with softdevice S130 V2.0.1 and want to use TWI.
Using the ble_beacon example I added the twi code from twi_sensor.
Shortly after calling TWI_Init(...
Hi,
during normal operation, my device shows a power consumption of 4.7mA.
Normal operation is:
accelerometer (lis2dh) detects a shake and wakes up the nrf51 via...
Hii ,
i am using customized board (chip : BT832).
err_code = sd_softdevice_enable(clock_source, softdevice_assertion_handler); hangs. it took some delay and after that...
Hi all,
I have seen a pair of questions ( this and this ) that I think have something to do with this, but didn't find a solution.
I have a custom board with a button...
I want to have an application similar to UART in the SDK example, with multiple peripherals.
I tried to modified existing UART example, but cannot make the central node...
I want to add the nrf52832 to my customized board and I am studing the possibilities for flashing it once that is located on the board. Is it possible to flash trhough the...
I have a board with some LEDs that are driven in the same way as with the nRF51 DK board (i.e. there is a resistor in series with the LED and you drive the pin low to turn...
In our testing we encounter some devices (Centrals with nrf52832), where the peer manager event PM_EVT_BONDED_PEER_CONNECTED contains a invalid peer id 0x4000 (allowed values...
I have a device the uses MSP430f169 and CC2500 RF controller for communication I need to replace the CC2500 RF controller with nRF51422 device.
As I understand an nRF51422...
