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...

Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
We are using the NR51422 to develop a BLE application. We reused the project “ble_app_hrm” from the SDK v6 and ran it using the NRF6310 board, everything is ok.
We just...
Hello Everyone, right now i use nrf51-dev kit and i want blinky code for that, in Keil i compile code and load in kit and it work fine but now i want to make code in eclipse...
I'm trying to debug the blinky example with SDK 7.1 using Eclipse Luna. Going through several threads here I could figure out configurations needed and build the app. I can...
Hi,
I have been trying to study how to implement support for over-the-air (OTA) updates in my current S110-based project. But I'm already stuck in the very beginning. How...
I am using softdevice and RTX at the same time.
RTX is using RTC1, softdevice is using RTC0, so no problem there.
But sd_softdevice_enable require a clock source as one...
Hi,
I have problem with nRF51 antenna orientation. I used nRF51 developement kit (mKIT) board and I had problem with communication if I just change a little inorientation...
Can I change the shared channel address (first one or first two bytes in the message) when the channel is open?
The manual says after opening the channel, send a broadcast...
Hi,
I rely on twi_hw_master (from sdk 7.1.0) to communicate with a sensor. It works without any issues without the SoftDevice. With the SoftDevice enabled, using TWI causes...
Would you recommend purchasing Red Dear Lab Development Board? Or should I get an EVKIT from Nordic Semiconductors?
Nordic Semiconductor eval kits are expensive and shipping...
I want to have it wireless capabilities into the cable, the receiver and transmitter antenna ports with shielded wire connected directly, so there will be a wireless signal...
hi, guys.
I'm prepareing the Korea certification, KC, with nRF51822 BLE system.
I'm progressing to get KC by certification agency.
Today, They will have RF signal test...
I was comparing the binaries for the S120 and S110 stacks and see the MBR is different.
I was under the impression that the MBR never changes and was thus expecting it...
Hi Nordic
We want to test radio parameter through IQxel . Now,we need a application software to control nrf51822(TX,TX,outpower,channal and so on ) . Can you recommend...
