I am trying to create an nRF8001 based application that will broadcast battery levels (pipes broadcast, set), and give out temperature data (pipe indicate - TX_ACK) to connected...
Hi,
I'm using redbearlab's nrf51822 board. It is a arduino compatible board and hence it is using 0,1 (mapped to 9 and 11 for nrf51822). How do I make printf print to this...
An external PA/LNA is used to extend range of nRF51822, and S110 is used for BLE, How to switch between PA and LNA? and how to disable PA/LNA when there isn't transceiving...
Hi...
Can anybody help me to run ble_peripheral example (ble_app_hrs for S130). I have build and load the code successfully but cant see the advertisement. But while debugging...
I am working with the nRF8001, and I'd like to create a services.h file that will let me broadcast battery level and as well as allow temperature to be read by a peer.

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...
Hi! We're preparing a medical device and are evaluating nRF5340 chip. We'd like to know when the chip and PDK will be production ready i.e. when Development Kit for nRF5340...
Hi,
One of my customers is applying LWM2M to their target application.
And they are trying to fix LOCAL PORT of LWM2M.
I heard that when end equipment is registered...
Hello
I use nrf52832 and mpu6050. I am trying to obtain values for pitch, roll, and yaw using mpu6050.
I don't know if it's because there's no magnetic sensor, but there...
Hello Everyone,
I recently started using NRF52840 dongle, I am trying to combine USB CDC ACM with Radio TX and RX examples. Individually the codes the running without any...
sd_ble_enable() returned NRF_ERROR_NO_MEM.
when I change this:
NRF_SDH_BLE_GATT_MAX_MTU_SIZE 23 to 247
NRF_SDH_BLE_GAP_DATA_LENGTH 27 to 251
here are turn...
Is there a chip with the same or even better specs then the nRF51822 but with more transmit power (at least 20 dBm)? https://infocenter.nordicsemi.com/pdf/nRF51822_PS_v3.1...
Hello,
my BLE application needs at least 5 different services to transmit different sensor data to a GATT client. I´m wondering how I can add that many UUIDs in my packet...
Hello Nordic Team,
We are currently working on a project that has nrf51822 and currently in the production stage. We are facing an issue with Bluetooth getting disconnected...
There is a bug in nrf_bootloader_wdt_init() in nrf_bootloader_wdt.c that can cause all DFUs to fail for long WDT reload values. I found this bug because I'm using a really...
Hello,
We are using nRF52832 to develop a door lock controller. As nRF52832 cannot work as NFC master, we use another chip to read M1 cards. Everything goes well, except...
I was under the impression that when the voltage was 0 in a GPIO pin, reading from that pin would return 0, and if there was any voltage going through the pin it would read...
I found a Q&A that shows 1 channel 2MHz pulse but i don't know how to generate 2 channel GPIO pulse with 2MHz frequency
(one channel is inverted pulse to another channel...
This is a bit of a weird question, but I thought maybe I could get a few useful inputs here.
I'm working on a mesh-like project where we need to facilitate communication...
