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.

Dear Nordic Team:
I used nrf52832 as my BLE IC, and an IC of Novatek as my MCU. They are connected by uart. Now I need to merge ble_dfu and serial_dfu on the version of...

I am getting error 65 'access violation' in Keil Uv5 and 4.
In IAR , I am getting 'User Error:Stack Pointer is setup into incorrect...
Hi,
I modiy the usbd_hid_generic example to tow endpoint by sdk15.0.When i use the USB testtool send some datas to usb deivce,the d atas cannot be read properly by NRF_USBD_EP_OK...
Hi, in our one project we are using nrf52832 radio to transmit the data packets. After transmitting the data packets, the nRF52832 chip need to disable the radio to minimize...
Using SDK 15.0.0, I have ported the peripheral/usbd example to custom hardware based on the nRF52840-QIAAC0.
In the nrf_drv_usbd_enable() function, execution hangs at

I'm communicating with a temperature sensor using I2C/TWI and I'm now trying to send that received data over BLE using the HTS service.
When I send a ble_hts_meas_t with...
Hello,
I am using nRF52 with ADS1292, and i am trying to sample at 8kHz with data throughput of 72kB/s, but some data is being randomly shifted giving me random spikes...
Hi Nordic Team,
I am requesting any block diagram level documentations - on a high level software architecture overview of SDK.
My goal is to understand how different...
Hello All,
I want to know Maximum External flash size supported by nrf52832 .
On which parameter Maximum size of external flash depends?
If it depends on usage, then...
Hello,
I'm currently using a bootloader based on the one included with SDK 15. We're close to mass production and I need to decide on how much space I should leave for the...
Hi,
I have designed a system that uses the SAADC to sample 3 analog inputs in scan mode at 8 KSPS, performs downsampling by a factor of 8 using the DSP, and sends the results...
Hello community and Nordic support.
Very briefly about my profile: I have worked with NRF52 chips in my previous company for about half a year and have a good understanding...
in my tutorial I need to implement an I2C or TWI sensor on a peripheral BLE. In SoftDevice Software in Example-> Peripheral there are 2 methods 1) twi_sensor or 2) twi_master_with_twis_slave...
I used nRF Mesh app both iOS and Android versions to communicate with
