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...

Hello,
Thank you for reading my question. My company and I have developed a BLE device for use with windows computers based on the nrf52810. The device pairs with windows...
I'm building my zephyr project for nRF5340, using west.
However, each time I change my code and re-build to try it, my PC (which is pretty recent) takes around 40-50s just...
Hey.
I have a problem where the task watchdog times out immediately.
I have taken the samples/basic/task_wdt sample and modified it a bit to simulate what I have in...

We have fairly regularly observed that the reset reason register gives two reasons for reset: software request and watchdog.
Is it plausible that these bits are genuinely...
Hi,
I am trying to communicate with nPM1300 PMIC board using NRF5340DK. I have made the connections and set up the overlay file as recommended. The I2C write (i2c_write_dt...
