Hi, I'm using the nRF8001 in an application that requires security so bonds to the remote client/central. My device supports firmware upgrades that may involve new nRF8001...
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 planning to use the nRF51822 and the s130 soft device to manage data coming back bluetooth sensor nodes. It is likely that there will be more than 8 peripherals, although...
The SoftwareSerial library allows GPIO pins to be used as TTL serial pins by bit banging.
The nRF5 suffers from the same problem that the Arduinos have. 1 UART.
Does...
Hello guys
I tried to start TWI bus and got a lot of questions. (NRF51 1422 AC)
I added necessary libraries, could You tell me what more i need to include in my code ...
Hi , We are using NRF52832 for our product .I have a small doubt in using GPIO . Can we use PORT and PIN events simultaneously at a time .
I need to configure some pins...
Hi,
I have three beacons in my setup:
One listening (R1) and two transmitting (T2, T3). T2 and T3 transmit packets with same length.
Say, T2 has started transmission...
Hello,
My system is one device with multiple host, these host will connected to the device on irregular basis.
The host action are listed below:

hi, i'm going to do some project with nrf51822 and SDK 6.0.0.
i just made up ble connection between phone and the chip.
and i want to send data some fixed time periods...
Hello,
I think there's a bug in the app_uart library in SDK 10 that occurs when the FIFO is enabled.
Using SDK nRF51_SDK_10.0.0_dc26b5e, I was trying to write data to...
I'd like to control a DC motor using PWM (PWM0, pretty straight forward).
To determine motor speed I disable the PWM every 5ms (TIMER1, pretty straight forward) and measure...
Hello,
Our application consists of 100 BLE static centrals and 1000 BLE moving peripherals. Is it possible to hide our BLE peripherals to be visible only by our centrals...
Hi,
i'm testing an application on nRF52, with nRF5_SDK_11.0.0-2.alpha and SoftDevice 132.
I took the ble_uart example and added a custom service with some characteristics...
Hello,
i'm trying a bluetooth connection between nrf UART v2.0 installed on my phone(android 4.4) and nRF 8001 (i'm usign nRF2740 card). My microcontroller is a STM32....
Hi.
I made my own board using nRF51822AC.
I want to connect this board to PCA10028.
There is Debug OUT port(P19).
Net names are EXT_VTG, EXT_GND_DETECT, EXT_SWDIO, EXT_SWDCLK...
Hi.
I'm using PCA10028, SDK10.0.0, S130.
Example code is using "ble_db_discovery_start()" function to discover peripheral.
In this function, there is "SRV_DISC_START_HANDLE...
