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.

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 see some interesting phenomena on the power profiler (with nRF52840) that would need some help to explain. I am using the ble_app_uart code from ble_peripheral folder in...

Hello everyone,
We're currently in the process of porting our code from the NRF51 to the NRF52 (both without any softdevices). Everything compiles and seems to be working...
Hi all,
I am making a device which involves using nfr52832(PCA10040) to communicate with a NAND flash through spi to store data acquired from the ADC. After all the data...
After performing the first ADC operation (4 channel scan, sample rate controlled from TIMER1), the power consumption stays at almost 4 mA for the nRF52832.
Why?

Hello, as oppose to S110, the function sd_ble_enable for S140 now includes one more parameter p_app_ram_base, which points to a value that stores the app base ram address...

My peripheral uses a generic sensor service which I use for various sensors. Most of the sensors only have one integer as value and can be abstracted the same, hence I made...
Does the Thingy:52 use the default transmit power of 0dBm? I didn't see anywhere that it could be changed from the app or that sd_ble_gap_tx_power_set was called anywhere...
Using Keil MDK Lite v 5.22, writing code in C for nRF52, with SDK 12.
