to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
I am trying to create an nRF8001 based application that will broadcast battery levels (pipes broadcast, set), and give out temperature data (pipe indicate - TX_ACK) to connected...
Hi,
We would like to implement a scenario that need two BLE devices,
One is Peripheral that able to broadcast and connectable,
another one is Central that able to scanning...
Hi,
I'm using nRF51 SDK v 5.1.0 with SoftDevice v6.0.0 on nRF51822.
I'm using the pstorage SDK module for flash operations.
I've found an issue with this module,...
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 (;;)
{

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...
