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:

Hi
We are using NRF52 and SDK 11 and S132.
The nrf52 acts as a central and selectively connects to the closest phones (ios) that are acting as a pheripheral.
For this...
hello,
nordic's engineers, need your help.
(1) the first problem : can not set VDD output to 3.3V
From nRF52840_Product_Specification_v0.5, it says:
High voltage mode...
Hi all! I am attempting to download a file from a web server to an NRF52832 using the Nordic IoT SDK version 9.0. Are there any good reference librarie? I found a few for...
Hi. I'm using nRF51822, SDK12.2.0, S130 v2.0.1.
I'm using nRF chip as Multi-connection Central and 1 Peripheral as well.
My event function is

I've tried everything I can find on this topic and I still cannot get P0.09 to behave as a GPIO pin. Does it have something to do with the way I'm attempting to initialize...
Hello,
I am working on a custom PCB with a nRF52832 and I've been unable to get the ON IDLE power under 480uA. Here are the basics regarding the setup

Hello! I'd like to know if S132 v3 implements the frequency hopping scheme defined by BLE.
I've read some documentation on Gazell, but from what I understood, that is a...
Whenever our battery runs to zero, or if we have a reset due to voltage droop, the unit will not auto-connect and the user is forced to "forget" the device in iOS bluetooth...
Hello,
i'm trying to use nRF UART driver (nrf_drv_uart) to implement a high level UART manager.
I followed indications on SDK documentation but it doesn't work and i think...
Working on a project to set up a bidirectional UART to SPI link over ESB with nRF52832 (PCA10040), using SDK 13.0.
Working from provided examples for PTX and PRX, I manage...
Hello,
I've implemented one custom service very similar with NUS. I have two peripherical devices that are running in two PCA10040 with S132 12.1, and one central device...
I have set up some code using the ESB example in SDK v12.2.0 I and am able to transmit and receive packets between two nrf51 dongles, with no issues. However, when I program...
Hi,
I did time measurements for packet transmission (notification) and saw only ~ 30 microseconds (about 1000 ticks with 0 prescale) difference between sending one or up...
Hi,
I am using nrf51822 chip. I am using RTC to generate irq with CC. Everything works fine for IOS and old Android version. New android version makes 2 things when I disconnect...
