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...
My application uses a NRF52 (SD132, SDK 15.0.0), very simple circuit and needs to be extremely low current consumption. I measured the current in conditions of BLE on and...
Hi, I'm having some issues with migrating from SDK12.1 to SDK16 while discovering services.
It seems to connect to Android without much issue, but on iOS the connection...
A project is currently utilizing an NXP module to access the SD card via 4-bit SDIO. I am exploring the feasibility of integrating an nRF52840-based module, and have a few...
I am trying to use the battery example in " /ncs/zephyr/samples/boards/nrf/battery" to measure my 3V coin cell via VDD. I am using P0.14 to enable a set load on VDD before...
I'm using a nRF52840 DK (PCA10056 2.0.1 2020,14 683193023) with an adafruit FTDI serial TTL-232 USB cable (part number P70C uses the FTDI -FT232R chip inside a translucent...

Hello,
I'm in the process of developing the HW board for a nRF5340-based product. I need the customer could update the firmware using a serial port (USB or Bluetooth is...
I am testing a number of boards with a QSPI memory module with NRF52840 chip.
The QSPI driver functions all return without error even if the chip is not present. What is...
I have made PCB 32mhz crystal footprint with error. I have used other khz frequency too. Now I can't solder 32mhz crystal is it possible to code nrf52832 and control various...
Hello,
I wanted to test the long range, so changed the primary and secondary PHY to BLE_GAP_PHY_CODED from BLE_GAP_PHY_1MBPS in the advertising_init() of the peripheral...
I'm trying to debug a Zephyr application on nrf52DK. However, due to the use of multi-threading (in Zephyr) I can't use J-Link Debug Server (as I'm used to). For executing...
Hi,
Can you please answer below queries.
1. Do you support CIoT EPS attach without PDN connectivity optimization? 2. Do you support UE Usage Type (HSS and Samsung MME...
In Nordic parlance, what is event and what is interrupt? To my understanding, in ARM parlance, events are signals that can be routed to NVIC to cause interrupts.
Basically...
Hi All,
the sdk17 documentation has the sad adc included (sad because a 12-bit adc turns out to have 9 effective bits and then with +-3% error on top of all that effectively...
