Suppose a nRF9E5 transmitter is set for continuous transmission on a channel.
A nRF9E5 receiver listening on that channel:
finds carrier and sets CD
finds address...
I will be deploying my nRF51822-powered devices into the field and the end user will not be able to have any physical access to, for example, power cycle the board. I need...
Hi,
We are using the ble_app_uart example in evaluation board to read data from some sensors and send it to the nRF UART V2.0 in Android 4.4. Every 20 ms I am trying to...

Hi
I try to program Insight ISP 130301 with a hex file, which works on nrf51 PCA10028. Unfortunately, it doesn't work. I try to loop for each pins and set it's state, and...
I'm trying cominicar me through Termite between the application plate (nRF51-Dk kit) and a device that supports BLE, but the connection between PC and the kit application...
I was working with IAR and SDK10.0 before. For some reason I have to transfer my project to Keil and SDK9.0. My program worked well for the old settings. While keeps got NRF_ERROR_SOC_NVIC_INTERRUPT_NOT_AVAILABLE...

Hello
I am doing a PCB design using nRF51422-QFAC chip. I did based on nRF51-DK but now I would like to change for a SMD antenna (2450AT18A100 from Johanson Tech.) instead...
Hi ,
I am working on one application in which i need to stream the ADC values over BLE to the mobile App. This should happen at very high rate i.e. 1000 samples per seconds...
Hello,
I'm trying to do something like ibeacon where data is pushed to any device listening, but I want to update the advertising data from raspberry pi 3 since it supports...
Hello,
I am working on an application where the nRF51 acts as both central and peripheral. The device is in permanent connection as peripheral while scanning for other devices...
