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 Nordic Forum!
We're currently tuning our antenna since we runed with some problems during our EMC testing.
In that regard, what is the impedance (both input and output...
Hi,
Is there no specific code of ble_app_uart_coexist meant for PCA 10056 and eventually s140?
Or will the same code work for the nRF52840 board?
I am using SES and...
I want to use the nordic USB peripheral drivers to allow for the initialization of multiple devices. The end result of the project will be to have a single nordic creating...
I am using the nRF52832 (on Rigado BMD-300 EVAL kit). I am using keil IDE and nRF GO to upload my compiled code to my device. I am using SKD 15.2.0. Using Windows 10.

I am migrating my project from SDK 15.0 to SDK 15.2. I was using CC310 to accelerate crypto in the bootloader.
While builiding the bootloader wit SDK 15.2, I got the error...
Hi team, Does the nordic chip receive a Bluetooth signal being communicated with a mouse, keyboard, cell phone, etc., and the sleep state (sd_app_evt_wait()) is canceled?...
Hi,
Can we use BLE 5 beacon with BLE 4 scanner?
As BLE 5 is long range which is my main concern. So, can I get that long range with BLE 4 scanner?
Thanks,
i have done the 10 dfu steps in DFU quick start guide when the boards are not far from each other it works but when i make them far a little
i mean one device in the area...
I am using a Sparkfun nRF52832 breakout. I was trying to install the Softdevice settings onto my Arduino IDE once I clicked on tools -> "nRF5 flash device " the blue ticking...
Current consumption of my code running RTC from LFCLK is ~2.5uA from the power profiler when I set the register values as. NRF_POWER->RAM[2].POWERCLR = 0x01; NRF_POWER->RAM...
Hi,
Currently evaluating SDK and have some issues, I would like to run some demos.
I believe I've managed to erase the "preconfigured" Firmware on the SDK, I have tried...
I am working on SDK-15.2, nRF52832 Dev board. My question is how to add write protected characteristic by KEY? Mean when we want to write something from peer device (smartphone...
1. I've noticed while using tools like NRFConnect that most BLE devices in my proximity do not include the device name in the advertising packet. My assumption is the developers...
