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 ;

Hi
I have firmware uing SDK 7.1 and SoftDevice 110. There is prepared bootloader for DFU, and update by very old nrfToolbox app works fine. But now I want to update this...
Using the Data Length Extension (DLE) feature in BLE v4.2, two nRF52 dev boards can achieve a maximum throughput of almost 800 kbps. I tested DLE with an iPhone 6 and the...
I am new to nRF ICs.
How to get 32.678KHz clock out from a pin? Is it possible? If yes, from which pin and how to configure it?
I am using 32.768KHZ external crystal fro...
I have designed several boards for the nRF51822-QFAA, namely with/for the Waveshare Core51822 module.
While one is working as expected - namely my "Orchid Lamp" (see links...
When softdevice S110 is used then bonding is not occuring (via nrf connect app to nrf51).but both devices get bonded when s130 is used?In Nrf connect app key matching failed...
Hi,
I have a working project where I use PWM driver with LEDs on the development board. I make use of the d52_starterkit.h where I have the following definitions:

Hi,
On a system reset, we want a mechanism to stay in bootloader for a short period before jumping in application. This way, if something is wrong in application that prevent...
Hi,
I am using ESB library for nRF52 microcontroller. At receiver i want to measure RSSI value of a packet. I got RRSI from nrf_esb_payload_t structure.
I am printing...
Hi,I have ibeacon (nRF51822) radioland-china.en.alibaba.com/.../long_range_300m_ibeacon_programable_nrf52822_beacons_bluetooth_4_0_tag_chip.html . I want to update the firmware...
Hi,
In my project i would like to save 100 bytes of information in RAM before going to System-off sleep mode.I have tested the example project given in sdk11 works okay.Have...
I am trying to read the battery level on a custom NRF52 board and I am getting a value that is around half of real voltage.
The same code works fine on NRF52 DK ( I was expecting...
I am looking at this example: github.com/.../main.c
In ble_evt_dispatch (line 315), this function forwards an BLE event to all of the modules. By looking at ble_evt_t,...
