How do I receive multiple signals simultaneously at a single receiver (433MHz) with multiple transmitters ?
I am working on a polling system. This one is similar to the audience...
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...
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...
I want to collect data for analysis sent from peripheral(ble_app_uart example), I connected peripheral device to app(nrf connect) and enabled service, now the data is sent...
