Hello.
Initially when reading the Gazell documentation I didn't think it'd be a problem but now in Keil seeing this has introduced some doubt whether it's a thing:

We would like to be able to calibrate the rRF9E5 ADC
Our proposal is to permanently fit voltage dividers, each using two precision resistors, on two of the ADC Ports and...
At some point in the past I had nrf51+gdb+breakpoints working just fine. I even have a bunch of __BKPT() calls in my various error handlers to trap into the debugger.
At...
Hi,
I'm trying to program nRF51822 Beacon Kit using nRF51DK. I'm trying to load the example ble_app_beacon to the beacon kit. After uploading SoftDevice 7.1.0, I try to...
Hello
I'm using the nRF51 DK and I have a UART over BLE link set up between the board and a phone with the nRF UART app. I'm trying to get the board to execute a particular...
Hello there guys i been reading your 100 pg PDF for awhile now and im yet to understand or realize how is it that i add/place/create a payload or data to send/Tx via Master...
I am interested in writing a BLE central that reads data from multiple BLE Nordic sensors. The BLE central will be running on Embedded Linux which uses the BlueZ stack.

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...
Hi,
I develop application on MBED platform with NRF52-DK. I figure out that pin "logic" on this board is interchanged. For example. I have LED connected to some pin. When...
Hello,
on my custom board I am trying to use pin P0.09 and P0.010 for interrupt-purposes. So I integrated the necessary adjustments as mentioned in this topic here , which...
