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...
I was wondering if the standalone nRF51822 microcontroller has support for i2c. If so which pins are supported. There doesn't seem to be any reference on i2c for the board...
Hi,
I bought a custom nrf52840 board and I need to program my firmware on this SOC with PCA10056 DK debug output port. in below you can see part of shematic of my custom...
I have some custom models in my mesh application in addition to SIG standard models. As can be seen with interactive_pyaci script when i read the composition data of my device...
Hi guys.
I'm working with a nRF52832 custom board.
In my case my board communicates with the LIS3DH through i2c protocol. In the other hand based on LIS3DH datasheet the...
Sir
about the
while(1)
{
sd_app_event_wait(); //stay here until a interrupt or connection occurs...
}
During the time that there is not a interrupt and no connections...
Hi,
I've recently switched some prototype code from using MQTT to a custom UDP-based protocol. What I noticed is that if I have the unit sleep for longer periods of time...
Is it allowed and possible to change the configuration of one pin from input to output chararacteristic (and back) during the normal work flow. I need this possibility for...
Howdy,
To achieve the lowest possible power consumption on the nrf9160, it is noted that it is necessary to disable the UARTs that are not used, when in sleep mode. However...
I'm unable to write a softdevice to my nrf52840, can someone please point me in the right direction?
I was able to program the board just fine using nRFGo Studio, but I...
Hi, I am using Adafruit BLE sniffer with nRF51822 v2 firmware and I am sniffing BLE packets in Wireshark. I can see my devices advertisement data when my device is in the...
Hello,
We are using the nrf connect Android app in order to scan and connect to ble peripherals.
The scan procedure is executed perfectly as we can identify and connect...
Hi In v5 one can advertise in le_coded and then a central can connect off the resulting AUX packet.
For the AUX_CONNECT packet the inter-packet delay is T_MAFS which is...
When I read Objective Product Specification v0.7.1, it seems external pull-up resistors are required.
However, when I use TWIM without them, it works out.
Do I need...
Hi Everyone,
I am using nRF52832 with SDK v14.2 and SD v5.0.0 on a custom chip.
Recently i included DFU support to our application. It turns out that secure bootloader...
Hi, I'm new to nRF52480 and Nordic SDK. It is first time for me when SDK has one big config file sdk_config.h. I started playing with examples (LEDs, serial I2C) and get it...
