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, in our one project we are using nrf52832 radio to transmit the data packets. After transmitting the data packets, the nRF52832 chip need to disable the radio to minimize...
Using SDK 15.0.0, I have ported the peripheral/usbd example to custom hardware based on the nRF52840-QIAAC0.
In the nrf_drv_usbd_enable() function, execution hangs at

I'm communicating with a temperature sensor using I2C/TWI and I'm now trying to send that received data over BLE using the HTS service.
When I send a ble_hts_meas_t with...
Hello,
I am using nRF52 with ADS1292, and i am trying to sample at 8kHz with data throughput of 72kB/s, but some data is being randomly shifted giving me random spikes...
Hi Nordic Team,
I am requesting any block diagram level documentations - on a high level software architecture overview of SDK.
My goal is to understand how different...
Hello All,
I want to know Maximum External flash size supported by nrf52832 .
On which parameter Maximum size of external flash depends?
If it depends on usage, then...
Hello,
I'm currently using a bootloader based on the one included with SDK 15. We're close to mass production and I need to decide on how much space I should leave for the...
Hi,
I have designed a system that uses the SAADC to sample 3 analog inputs in scan mode at 8 KSPS, performs downsampling by a factor of 8 using the DSP, and sends the results...
Hello community and Nordic support.
Very briefly about my profile: I have worked with NRF52 chips in my previous company for about half a year and have a good understanding...
in my tutorial I need to implement an I2C or TWI sensor on a peripheral BLE. In SoftDevice Software in Example-> Peripheral there are 2 methods 1) twi_sensor or 2) twi_master_with_twis_slave...
I used nRF Mesh app both iOS and Android versions to communicate with

The system consist of two nRF52832, one acting as SPIM and the other one as SPIS. I hace created a while loop always asking for certain amount of bytes but the MISO line on...
Hello, I am new to nRF micro-controllers and using Netbeans. I have cloned the repo of a project I would like to run, which builds successfully, and am getting the following...
Two questions. 1) What is the point of the watchdog ISR? In the Ambiq Apollo 2 microcontroller, the watchdog ISR fires and if the CPU doesn't pet the watchdog slightly after...
