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 There,
We are using two microprocessors in our project is kind of activity tracker which is stm32l (M3) with accelerometer, temprature sensor and SPI flash connected...
I'd like to start developing with the nRF51822, and have found the two kits supplied by Nordic, the nRF51822 Evaluation Kit and the nRF51822 Development Kit. What's the difference...
I am being told by a RF test lab that I need to provide a sample which has the following modes:
BLE "with modulation"
BLE "without modulation"
ANT+ "with modulation"

Hi all,
When I test the UART demo progrem, I cut off the power supply of the board,but the RX pin is still connected to the PC TX pin,and I measures a voltage on the VDD...
Hi,
I need to use watchdog as a timer, and I can enter WDT_IRQHandler for now. Can I stop watchdog reset the system in this IRQHandler? So I can counting like a timer.

Dear all
is there any possibility to use PC to test the nrf51822, Instead of Android/ios app?
preferably a lib to be used with Java, so one can have some test cases...
I want to sync some information and control code between Nordic and our CPU(ST), so I need to study serialization function. But I only have serialization function sample code...
Hi
I'm going to use a module that uses nRF51422 and that has an adapter to be soldered as a SMD in a circuit to mimic the footprint of an AP2 module. The adapter only has...
I'm implementing my own equivalent of hci_dfu_send_hex;
There is not enough information in the documentation on how these packets are constructed.
I found that the first...
Dear community
I've got this nice "white-blue" Kit, neat toolbox to configure the tag and run it.
Now, for Battery/ImmediateAlert profiles and other parts seems to be...
Hi,
How can i test the proximity application with the use of nexus4 smart phone and nrf51822 evaluation board?
We already tested the ios proximity application which are...
Hi community,
Till now I developed some BLE applications on the TI-controller CC2540, but for my new project, it seems to bee not fast enough. So I'm seaching for an alternative...
Im mainly considerate about ANdroid and iOS devices ,I understand this is also dependent upon profile support over the android and iOS devices but this should not be an issue...
in my pca10001 board,
once i made led pin 18 and 19 pin as internal pull up.
led is not on,and i probe it also but not high.
here my config in blinky example.
