Hello,
I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
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,
Both examples were built failed in Keil due to exceeding 32K trial limitation. Is there any way to reduce the size? Or any suggestion?
Platform: nRF52DK

I am working on a project using a BLE Nano and Nordic sdk 8.1. When I compile my application and flash it to the device my program runs exactly how expected. If I unplug the...
I use the nrf52832.
In the beginning,I can download the code and it works well.
And suddenly,Keil told me "No Cortex-M SW Device Found",when I change a new chip it can work...

Hi, i'am working on a custom board on which there is two led drive by a led driver.
The two leds are wiring to be drive by pins P0.14 and P0.15, but unfortunately these...
Hello! I am using a nRF52832 device, along with SDK 12.1.0 and S132 v3.0.0. Data is being sent data through BLE and received on an Android phone.
After some tests I noticed...
I need to have a Central device physically connected (via UART) to a sensor. Data is collected from the sensor and sent to a number of Peripheral devices which use the data...
Take a look at these screenshots. With the trigger enabled, the average current consumption is reported at 13.21uA. With the trigger disabled , the average current consumption...
Dear Nordic,
I want to know if it is possible to send asynchronous data type from a slave node to a master node (master node would be in continuous scanning mode). Reading...
Here is my problem. I want to disable uart when there is no data coming into MCU.
I used IO LotoHi event to enable uart Rx. After finish data receiving, I disable Uart.

I've modded the PCA10040 DK for current measurement with an ampere-meter (TTi 1604), using a program which turns an LED on and off every 5 seconds. The measured current stays...
I am using an LG G5 and my co worker let me use a google pixel. I tried using the s132 softdevice along with the BLE UART example code from 12.2.0, I get the device is not...
I'm aware of GATT's Profile, Service and Characteristic.
And also, for GATT_Server, GATT_Client it can be Central or Peripheral. (As I manually set it.)
And also, the...
hi
I am using nRF51822(from waveshare). previously i was able to program my device with nRFgo Studio. But I am facing a problem now. I programmed my device with radio transmitter...
