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,
I am using the secure bootloader as a template and I want to use the inactivity timeout to shutdown after 10 minutes.
I saw that the limit should be 60000000 ms (according...
SDK: nRF5 SDK for Thread and Zigbee 1.0.0
I have code for the SAADC based on the Low Power SAADC example here .
I have modified it to sample 4 inputs, and changed the...
Hi,
I would like to check battery level using the SAADC of the nrf52840.
Assuming the voltage is less than 3.6V, do I need to have a resistor between the battery and the...
HI,
I am new to IoS development with NRF.
I am having NRF52840 DK, IoS device. I want to implement USB HID device application (similar to pulse/Gluco meter ) on IOS. I...
Hi,
I am not able to compile the SDK example by using SES for ARM V3.52.
I got one error which shown below:
It pointed to the link ldr r0, =%4

Hi,
I am using fatfs of nRF5_SDK_15.0.0_a53641a.
I am writing a program with keil.
I am currently doing SPI communication with BLENanov2(nRF52832) and SD card with...
Hi,
I am implementing the UART on NRF52840. TX works but the RX doesnot. While debugging, I noticed that STARTRX task register is not getting set due to which the RXDRDY...
Hi Sir
We'd want to do RX testing with DTM mode, however, the dtm example code looks can't report receive data or total packets counts,
So that, we don't know how to determine...
Hello,
I'm using the nrf15822 chip and am using the ble_app_uart example from nrf5_sdk_12.2.0.
I know softdevice will automatically generate random numbers through RNG...
I've been told due to PAN 58 it is not possible to use EASY DMA with nrf52832 without switching to the deprecated SPI driver. Is there a workaround that allows the use of...
Hello,
We are going start custom PCB design by using nRF52840 chip and SDK 15.0, but confused for use 3rd party nRF52840 modules or design complete custom PCB using componenets...
Hi,
Despite knowing a fair bit of the theory of wireless comms (mainly PHY and MAC), I'm brand new to actual hardware configuration/protocol development, so please be gentle...
As a master device with a whitelist there is a limitation on how many slave devices can be connected. If i am correct, other than whitelist there is no restriction to the...
Hi,
How do I receive data from host (computer) on my BLE device(Nordic board)? I want to use a simple open source HID API to send data to Nordic board and glow an led or...
