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'm currently using ble_advdata_set to update the ble advert data packet. Before transmission I use the ble_radio_notification event . In this event for test purposes a single...
Hi,
I'm using a nRF51422+nRF6310 and I need to use SPI in order to connect with some devices. I am trying to run the example "spi_master_example_with_spi_slave" but I found...

Hi, i am currently modifikat a working ANT-System (Master with multiple Slaves) with the NRF51422 and Softdevie 1.0 to be robust against in band disrupters. My idea is to...
I have an application based on the ble_HID_keyboard_template (uses STM32F072 instead of Arduino). The first time I pair my iPhone 5 (iOS 8.1.1) with the nRF8001, everything...
Hi,
I'm using nRF51422 with S310 and ble_app_hrs example application.
Thus I can simulate a Heart Rate Sensor with the board and get data on an Android phone with the...
Hi all! May I use another quartz instead of 16 MHz? Will the output frequency equal to 2.4GHz/16, if I will be use the 1 MHz quartz? Or IC will not work? Is it possible to...
I need to evaluate the real consumption of current for BLE events on RF81822. The HFCLK is 16MHz and the 32kHz clock is external.

Hi, I am using S120 1.0.0 and SDK 6.0.0. Learning the sample project 'ble_app_multilink_central'.
I already got a peripheral device with NUS service. The central device...
I am new to this great platform and am struggling with getting my PIR sensor connected to my DK. I wonder if some of you experts could give me some pointers on how to go about...
Hello, I build a BLE 6LoWPAN environment on my raspberry pi with Kernel 3.18.3 and connect a BLE Dongle. The BLE Node is Arch BLE ( www.seeedstudio.com/.../Arch-BLE-p-1998...
Hi, I have two different types of nRF24L01+ modules, both behave differently.
The "troublesome" module always has TX_DS asserted after a transmit, which is the same behavior...
Hi,
I am using the SPI Master 1 to control an EEPROM. I used the spi_example project to help get the code working. It all works fine if the code that initiates the SPI...
We have designed a differential antenna for the nRF51822 CEAA chip.
Each of the RF output connects through a matching circuit to each one of the two 50-ohm to ground end...
