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...
Hi,
we used NRF_UARTE_Type POWER for the "peripheral power control" of the UART interface on nrf51 - works fine.
After trying to port the nrf51 to nrf52 I found out...
The question is: how to completely turn off PWM in SoftDevice?
I am using the libraries nrf_pwm.h and nrf_pwm.c in this repo for PWM with SoftDevice. Everything seems to...
Hi,
when trying to update the firmware with current nRF Master Control Panel (version 1.10), the update finishes successfully, but the firmware does not run.
The problem...
I've tried a trivial example (blinky-like, compiled by gcc using proper startup and ld scripts) on nRF52 devkit, but I always only get hard fault.
Debugging through the reset...
The nRF24L01 dataseet V2 (the most recent I think?) states (p.23) that the nRF24L01 can operate on frequencies from 2.400GHz to 2.525GHz . The channel steps are stated as...
I am completely confused by the nRF51 UART. I'm trying to port code originally written for an STM32 (another cortex chip). There, I define an interrupt, enable the RXRDY or...
Hi,
I need to have two different interrupt handler for one pin?
For LOTOHI one handler and for HITOLO another handler, how to do that?
Here is what i did until now...
Hello Nordic and fellow developers
While implementing bonding into an application based on S130 I found it necessary to test on the role of a given connection. Different...
I am getting device id of peripheral on central and then getting it displayed on hypertermianl hyperterminal using ble app multilink perihperal code with multilink central...
Hi Everyone,
I have what I hope is a simple questions. I am creating a piece of hardware that will act as the peripheral to a central iOS app in regards to a standard BLE...
Is there any construction available in the SDK, to achieve printing functions, with an undefined number of parameters ? The classic example :
#ifdef CONFIG_DEBUG
#define...
Hello,
I've ready the final S130 spefication and it states that the advertiser is started as early as possible and that i runs asynchronously to all other roles. Now I...
