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 all.
I am making a PCB for nRF51822. My PCB need is to talk with iPhone for BLE Proximity application. Also I need to control a LED from iPhone. And I need to get low...
In short: Is it feasible to use RSSI values when tuning the antenna?
I have a custom board with an nRF51422 on which I have designed the RF part to be as much as possibly...
Any suggestions for handling a bricked custom board?
I'm pretty sure I know where the problem is in my code, but now I can't reprogram the board. I did have this happen...
Hi, I'm developing an BLE application using nrf51822.
I have a BLE security issue to discuss.
(Actually I don't have much network security background...)
In our application...
I'm using PCA100001 board with pure-gcc Makefile and s110_nrf51822_5.2.1_softdevice.
And I'm writing simple code customizing s110 samples like below:
static void ble_stack_init...
Hi
Does the NRF51822 support ANT and where would be a good place to understand how to implement ANT ? I also want to know where I can get more information regarding the...
Hello community, first time posting a question so please try and forgive any future mistakes.
anyways im new to using the keil IDE and am have some problems. I have dug...
I am using pca10001 board and started my development from nrf6310/s110/ble_app_hids_keyboard.
SDK version is 6.0.0. I have successfully tested my device with (MCP) Master...
Hi,
I am very new to BlueTooth technology. Currently i'm testing the nRF51822 evaluation kit to see if the BLE module can be used for a specific project. I've tried several...
I have a schematic in which Balun is connected as a matching network to Ant1&Ant2 pins making the output impedance 50 ohms. Now i want to connect an Antennae to it which is...
Pages 51 and 53 of the nRF8001 Product Specification (v1.2) show a reference design for a balun network in which capacitor C4 is listed with a value of "N/C". The component...
Just in case no one has ever given any feedback WRT Eclipse, Id like to be the first. My experience is using it with all the features for a NRF51822 project, and it kind of...
Seeing, that the nRF51822 was specified to operate with a 16 MHz crystal or oscillator. Is that also the clock what the Cortex-M0 core runs or is there a PLL to increase the...
Dear Support Team,
I'm working on a BLE application and the most stuff works well but now I had a spurious application crash at "src\ll_lm.s0.c: 1038". Could you please...
Hi There,
We referancing the PCA10000 for antenna circuit design. We are going to use 0.8mm FR4 PCB however we couldnt find out the Thickness of copper conductor. And it...
