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.

Hi,
I'm trying to get S110 softdevice (v8.0.0) working with RIOT. I had some issues (I couldn't initialize TIMER1 or TIMER2 until softdevice is setup & enabled) but I think...
Hi, I would like to put a nrf51822 device into system off mode and wake it up with a GPIO transition from high to low.
I would like to measure the press time of the button...
I'm using JLinkExe ( J link commander ) for Linux to flash the application firmware on NRF51822_QF_AA target. The following have worked so far, but I'd like to confirm and...
Hi,
I am upgrading to SDK 11.0.0 and S130 v2.0.0 from SDK 9.0.0 and S130 1.0.0 and I am stuck with an error when I call sd_ble_gap_adv_start. Here's the code that now fails...
I have the following two lines with pin 21 not connected to anything:
nrf_gpio_cfg_input(21, NRF_GPIO_PIN_PULLUP);
uint32_t value = nrf_gpio_pin_read(21);
I would...
Hello!
I'm trying to flash my SeeedStudio Tiny BLE board (nRF51822 QFAA) with SoftDevice S110 using Keil but it doesn't look like it's going to let me. I'm just getting...
Hi,
i am having some trouble getting my nRF52 DK (S132) to read a value provided by the nRF51 dongle(S130).
First of all, i am very new to this whole Bluetooth thing so...
Hello!
I'm trying to read 16 bit ADC Value on nRF Master app instead of only 8 bit, and I know that there is the example code on github which is only send me the 8 bit...
We have a new daughter board connected via I2C to an Atmel controller. What we need to do is load the right softstack onto the NRF and then send the needed commands to tell...
