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...
I'm trying to implement channel scanning in our nrf24lu1p based USB dongle.
I'm following the specs and basically loop though each channel ;

I was redefining the init packet and when it came time to generate the nano-pb files, it looks like there is a fair amount of difference in the newly auto generated pb.c and...
Sorry if these questions are discussed already. I'm a newbie to Bluetooth project. Let me explain in brief. I have a central and peripheral device. I am transmitting 10samples...
After quite a few difficulties getting Keilv5 to work with the included examples with no responses ( devzone.nordicsemi.com/.../) I decided to give Eclipse a shot.
This...
Good day All,
We are in the process off procuring a project using nRF52, and I need to find out some important things. Are there any costs in using any of the libraries...
I am using nrf52840 module(peripheral) for transmitting 10samples/10ms and central device as the same nrf52840 for receiving the samples. Although I receive the packets, there...
Hello,
I'm working on an application in which I have to dynamically switch between a TWI master peripheral and SPI master peripheral that use the same peripheral ID (our...
I have an NRF24LE1 transmitter using ESB. It is sending a static payload of 10 bytes every sec.
The other configurations on the transmitter are: RF channel:2, CRC: 1 byte...
Hi,
i'm wondering if there is any IC (for example nRF52832) that can reach a range up to 155 meters available within the Nordic semiconductor catalog ?
i know that the...
In nRF5 SDK 12.1.0 a bug was fixed in nrf_drv_wdt_init(). Watchdog timeout could not be larger than 131 seconds because of (x * 32768) multiplication before. This bug is again...
In the spec it says that the typical ramp up time is 140us (or 40us in fast mode). But there is no details on maximum or minimum. What is the true tolerance on this value...
We are building a simple project, let 51822 connect the mobile, once per second. We found that the Tx power of 51822 is getting weaker and weaker (view the voltage over a...
I have a nrf51 dongle and would like to use PWM on 3 pins.
Managed to get it working on pins 15 and 16, but somehow pins from 17 to 20 just don't work.
For example: I set...
Hi,
I have two nrf52840 boards and I am using the ble_app_att_mtu_throughput test app. The tests seem to be working OK, but I am not getting the throughput I was expecting...
