Hi,
As the subject says, I have an nRF54LM20A acting as a SPI slave. When I perform a call to spi_transceive_cb(), I don't have any data for TX (i.e. MISO). This runs until...
Hi Sirs
We are planning to use the nRF54LM20A/B together with the nRF21540 FEM in our design, and we have a few technical questions regarding TX power control and FEM...
Hi Nordic Support Team,
We are currently evaluating the nRF54L05 DFU single-slot sample in NCS v3.3.0.
Our question is: Is it technically possible to configure the single...
Hi,
I'm using the published nRF54L15 DK hardware files and noticed something that I don't understand.
On the nPM1300 section of the schematic and PCB:
Pin 20 ( VSYS...
we are developing solutions with PMIC type=PM1300, we eager to know the internal LDOs PSRR.
i have read 171 page of PM1300 datasheet, but cannot find PSRR data or the PSRR...
nRF54L15 PDM clock runs at ~1/32 of expected (PCLK1M instead of PCLK32M) on a custom board - works on DK
Summary
On a custom nRF54L15 board, the PDM peripheral clock ...
HI
I am currently using the nRF54L15 chip with NCS 3.2.1, carrying out secondary development based on the periodic_sync_conn sample project. I intend to adjust the transmit...
Hi
In the product specification the S120 softdevice it is mentioned, that the S120 will support central and broadcaster role at the same time. This is exactly what we need...
I've cut the BLE proximity app example code back to doing nothing more than this:
int main(void)
{
uint32_t err_code;
leds_init();
for (;;)
{
power_manage...
It takes about 30s after I power my nrf51822 DK with ble_app_hids_mouse demo, how can I short it less than 10s ?
In the code there is a line
"#define NEXT_CONN_PARAMS_UPDATE_DELAY...
Would like to know whether you have a diagram for the RF pattern for nRF24L01. Like whether the node can receive other nRF signals 360 degrees around or should be at some...
Hi, I need to select the values for the crystal capacitors (C1 & C2) for a nRF51422 pcb.
From page 9 of "Crystal Oscillator Design Considerations" I see:
C1' = C1 +...
Hello,
I'm assessing various ways to authenticate/secure a connection with BLE on Nordic nrf51822. Our goal is to enable authenticated modification of a few values in a...
Hi
I see this in our own firmware and also in the sample HRS on the PCA10001
(If you try with the HRS app, then modify the app so that on BLE_GAP_EVT_DISCONNECTED instead...
I'm trying to get a simple, single shot timer working. The debugger never stops at a breakpoint set in my handler function, and an LED turned on in that function never lights...
Hi
i'm using nRF51822 with twi_hw_master from gzll library from SDK v4.4.2.33551. Code is compiling and linking, but not working. Gazell transmissions don't work when twi_hw_master...
Hello.
I want to protect nRF51822 ADC input from emergency case of overvoltage (up to 24V).
I don't want to use external diodes as any GPIO pin already has internal clamping...
When I use ble_app_hids_mouse demo to test my mouse sensor, it seems that mouse arrow will delay about 300ms to start send data ,at the beginning of movement.
When I cut...
Hi all,
I bought dev kit for nrf51822.
I got serial number for some projects.
Now I do not know where to build those project?
Should I use ukeil? How to install new device...
Hello,
I need to store some data to flash, and am starting to review pstorage. My question: how does pstorage know which blocks belong to which application? It appears...
We need some (5~10 pieces) nRF51822-CEAA-R (3.5x3.8mm 64 ball wafer-level chip-scale packages (WLCSP)) for prototyping. Where can we buy these?
The main suppliers like mouser...
