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.

Hi! I am currently doing my project on BLE beacons. I am using nordic's nrf51822 and waveshare ble400.
I am using a blackmagic probe instead of jlink to program it using...
Hello,
my sdk is from nRF5_SDK_12.3.0_d7731ad, I added the dfu service to the ble_app_uart project on nrf51822QFAC,but it just could run to serviive_init() function and...
I am using a bootloader based on the secure serial DFU bootloader example in SDK 13 and tested it on a development kit. I noticed that hardware flow control is enabled in...

1,
Conditions: Two dma buffers are used, SHORT = TASK_STARTRX, 1M baud rate (10us / B)
Phenomenon: At END_RX interrupt, I called GPIO0 = low. With the logic...
Bluetooth Mesh Glossary of Terms mentions 3 different kinds of addresses: Unicast Addresses , Group Addresses and Virtual Addresses .
I think I understand what a Unicast...
I'm developing firmware for the nRF52832 in eclipse, and since I'm using the NFC pins as GPIOs I need to include the "CONFIG_NFCT_PINS_AS_GPIOS" cflag in my Makefile. However...
I've noticed that if I have data queued to go out over the uart (using app_uart_fifo) if I do an fds_record_update the UART TX is effected. You can see what's happening in...
I have put my code developed on a nRF52 dk on a custom board that is based on a ISP1507 CPU. We are having higher current consumption than expected, I use the exact same code...
Hi There,
In company we are working with nRF8001 (currently C revision) and we want to send some custom data in an advertising packet. However, when C revision is selected...
From the S132 5.1.0 specification, I expect that its RAM usage should be only 0x1228 bytes plus ATTR_TAB_SIZE. However, when I compile two of the example projects using IAR...
I am working on a project in Nordic SDK 8.1 that requires using a timer. I am confused where I need to define the timer though (using APP_TIMER_DEF). If I put it right after...
I am working with the SDK 12, nrf52832 low_power_pwm example. I am concerned about the power consumption I am measuring.
I am trying to produce a 1khz PWM for an LED (the...
Howdy,
I am having difficulties writing to NVRAM (reading appears to be fine and is reporting 0xFF's everwhere). I am using a rather old SDK and SoftDevice 110 (version...
