Hi We have an application where we what to read i2c sensor data over the air to an iPhone. We've taken ble_app_uart_S130 project and grafted in some twi_hardware code. There...
I am interested in the S130 ability to hold 3 central -> peripheral links over BLE, and am looking for some evidence that this has been accomplished with extremely low-power...
I'm trying to implement channel scanning in our nrf24lu1p based USB dongle.
I'm following the specs and basically loop though each channel ;

Hi,
I am using the NRF8001 in UART mode and attempting to bond with my android device (Lollipop 5.0 Nexus 6).
i am using the nordic arduino sdk which is found here:...
Hi, I'm using the nRF8001 in an application that requires security so bonds to the remote client/central. My device supports firmware upgrades that may involve new nRF8001...
Hello.
Initially when reading the Gazell documentation I didn't think it'd be a problem but now in Keil seeing this has introduced some doubt whether it's a thing:

When using proprietary radio protocols only (Shockburst/Gazell) are there any difference between nRF514 and nRF518 chips? Do they behave totally equal so they can be used...
I need to send a data package when radio is ON every time
but I try to send data by "sd_ble_gatts_hvx()" I find it can not work,it seems that I can't call this API to send...
Hi
i'm new in dev zone and i have a question
now i work with nRF8001 and i want to design a pcb for it.
I want to reduce the BOM and for this i want to use only the internal...
Hi,
I am trying to use the DFU example provided in SDK 5.1.0. I have built the example using gcc 4.7.x, and i am also using softdevices 5.2.1. The DFU example has been...
Hi,
I've the need to write a characteristic value of 65 bytes, from my central device (iPhone/iPad) to a nRF51822 peripheral device, so I was looking at this document for...
Hi, sorry if this is a dumb question. I've just ordered some development kits and maybe that will answer the question, but i'm being a bit impatient!
I want to put an nrf51422...
My sensor is off-standard,so I have to use gpio to read and write my sensor.
Gpio IIC will take about 0.5ms to get data.
My app need send data every 7.5ms,it seems that...
Hi all,
In my project ,I use the SPI to communication between nRF51822 and STM32,but I don't know
how does the heart_rate data transmit to BLE stack.
I am confused...
