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 have ported the example project "nrf_crypto_aes_pca10056" to my one project. But now I'm not able to building the project anymore. Segger Embedded Studio will show...

I am in the board design phase of my project. I use Arduino boards (Due & Uno) with SPI. I read that the nRF24L series is not recommended for future projects....
Hi,
So I am using nRF51822 chip to develop our products. We have two motors attacked to our PCB and we want to control the pulse with low power PWM. We want to control...
Hi...
i want to read the data from another board using serial uart .. how to write the command to check the data is available ... in arduino i written like this how to write...
Hello,
I used to use two nRF52810 for testing.
Using Timeslot (BLE+ESB), one of the 52810 paired mobile phones Bluetooth simultaneously sends the ESB.
Another 52810...
What are all the configuration options necessary to configure the nRF9160 as a SPI slave? I'm working with a custom board and have specific DTS files I'm working with. Here...
Hi Nordic Team,
I'm quite confused and can't find a concrete answer so far on the forum, if it is a MUST to kick-off a certification at the Bluetooth SIG Group or not, if...
nRF52840 SDK 15.2
I want to control the power of sensor, so I configurate the pin like this:
nrf_gpio_cfg(AFE4403_PIN_PWR_EN, NRF_GPIO_PIN_DIR_OUTPUT, NRF_GPIO_PIN_INPUT_DISCONNECT...
HI,
I am using ".\nRF5_SDK_15.3.0_59ac345\examples\peripheral\wdt" to test “watch dog timer function.
My use case is:
1. If the program is not execute over following...
I have developed ble periphleral device to send 20byte long at every five seconds to the central. Because connecting to serial to PC, I didn't realize the device cannot not...
Hi,
I need to run RTC simultaneously with Softdevice without external low frequency clock source (32.768kHz oscillator).
I used following settings to setup RTC,
RTC_ENABLED...
I am trying to make a central device that is similar to the NUS central example in the SDK. I have a function that is the same as ble_nus_chars_received_uart_print to print...
In the ESB stack, only a sub-set of available transmitter powers are enumerated in nrf_esb_tx_power_t.
Is this deliberate? The hardware supports a much wider range of values...
