I am analyzing the power consumption of a custom board with an nRF52833 BLE SOC and nRF21540 FEM for different BLE parameters. In one of my experiments I vary the amounts...
Is there a straightforward way to output the frequency of the 32.768kHz crystal oscillator to a GPIO pin? The motive for this request is to verify the crystal frequency without...
Hello,
I'm developing for nRF54L15 the application with the NSIB + MCUBoot. I have a problem with fprotect in mcuboot returning EINVAL error. That happens due to limitation...
Hi all,
do different settings of SAADC RESOLUTION register affect Conversion Time t CONV ? I cannot find any dependency - the only value given for t CONV is 2 µs typ (7...

Hello:
It appears (although I am not 100% certain) that there is a small delay (< 10 usecs) between EVENTS_END in the radio and MICSTATUS in the CCM. I believe I have read...
Hi,
I've got an application running on an nRF52, and it's calling sd_app_evt_wait() from the main loop - and it's staying in that function pretty much all the time.

I don't have a 32KHz crystal on my board (using the stock Rigado module) and power isn't an issue as the board is mains powered in operation, so I was intending on using the...
I found a alpha version of softdevice v3.0 (s132_nrf52_3.0.0-2.alpha.zip), and it supports MTU_SIZE > 23 bytes, but there is no SDK (current version is v11) supports it. When...
We have two nRF51822 chips with cleared contents in FICR, e.g. addresses 0x10000000 - 0x100000FF are 0xFFFFFFFF.
UICR works as expected.
Chips execute code.
Radio performance...

On nrf51 I was using:
pre flash: w4 4001e504 1
erase all: w4 4001e504 2\n w4 4001e50c 1\n sleep 100
pin reset: w4 40000544 1
Is it still the same for nrf52...
