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...
Hello,
I would like to develop a custom key sharing algorithm for nRF8001 chips. As far as I have understood the only way to use full 128-bit temporary key (TK) is OOB...
Good Moring engineers.
I just got nRF24LE . I am wondering the timer2 only provide 2 seconds long period ?
I want my project nRF24LE sleep as long as possible , at less...
I am using an RTC for other purposes that exposes a buffered 32kHz clock. I am considering using the buffered (rail-to-rail) for also the LF timebase of the nRF51. The drive...
I've just discovered that the Jlink LITE programmer can not program my custom PCB because it runs at 2.7V.
Does the nRF51-DK board support programming an external target...
Hi....
We are working on PCA10028 DK with S130 softdevice version 0.9.0 alpha. Could you tell me about the release of stable SD S130. Hope it will be soon.
Hey,
Is it possible to use the NRF51822 for connectivity together with Arduino, and if so are there any easy instructions as to how to do so? I am looking something on...
Hello I was wondering if I can use both the proprietary protocol 2.4 Ghz ( I understood the one to use for the new projects is Gazell ) and the Blueotooth smart on the nRF51422...
Recently,I met a problem when I used Gazell mode. Before, i used the GPIOTE to collection PPM receiver 's length of time, when I also use the gpiote and wireless data transmitting...
Hello , i have been following the ANCS tutorial and have managed to pair it with my iOS device. I am using the Nrf8001 with an arduino. I have read up many articles about...
I have seen several good questions and answers on this forum regarding the use of a PA for extending range of the nRF51422/nRF51822 devices. I have a battery-powered application...
Hello everybody,
We are using a nRF51288 with an external DCDC converter. VDD and AVDD is bridged, DCC is not connected.
The software is working in Peripheral mode, S110...
hello,
I recently purchased a NRF51 dongle and NRF51 DK. I was working with older version of NRF51 development kit. I did n't get any information in the user guide provided...
Hello,
when using the S130 with multiple connections and sporadic advertisement and scan procedures, I get a connection timeout after a few minutes, now I must know, how...
Hi,
Im using an app_timer in my application to create a timeout for UART read (im not using SoftDevice).
On my board I have USB and battery power, so at the moment when...
