Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
Hi.
I am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
Hello,
Is there a way to set the OOB key while using the master control panel windows software?
Edit: and if not, is there a quick method to test a peripheral's OOB...
Hello!
1)There is problem with nrf_ble_uart. On sdk 4.4 work well, but sdk 5.1 the same code is not working.
What changes were made in the sdk or maybe there is a ready...
Hi I have built a custom NRF8001 board and I'm debugging a problem.
The main microcontroller works fine (atmega32u4) but the RDYN line never goes low to start the setup...
I am starting development on the nRF51422. I noticed that for the non-ANT sample code (blinky and UART), a gcc makefile and windows batch files are provided for compilation...
Hi,
Does the heart rate demo in SDK v4.4.0 work with SD v6.0.0? I'm using the QFAAC0 revision of the NRF51822. The demo works fine with SD v5.2.0. Is there anything special...
So far I haven't run across any code examples that will switch the BLE (S110) stack in and out. I'm looking to test enabling and disabling of the softdevice to see how that...
I'm reading AD-converter data usin nRF51822 SPI-Master. BLE-stack is active so I can't use
interrupts with SPI. I get data every 2 ms. Sometimes Events are delayed so long...
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 (;;)
{
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...
