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 ;

Are there any options today that include Sub GHz, Bluetooth, and LTE for Mesh Networks??
I am thinking of a Gateway with multiple sensors communicating through Sub 1Ghz...
Hello,
We are trying to evaluate the HomeKit SDK with our nRF52832 BLE modules. The "Lock(static)" sample application doesn't work with Apple 'Home' App on iPhone 8+. The...
I'm currently evaluating different platforms, that run on the nrf52832 soc, like Nordic Semiconductors own firmware, as well as Zephyr, myNewt and mBed. As you guys from ...
Dear sirs
Good evening !
I´m using the RF24.h library in order to develop a system that comunicates in peer-to-peer mode.
When I transmit 3 bytes towards a receiver...
I'm hoping someone can tell me if I'm on the right track. Do I understand correctly that on an nrf51, the LPCOMP can be configured to wake the processor on an analog input...
Hello,
I was wondering how is calcualted or read on the Thingy firmware the variable w for the quaternion used in the Gyroscope readings.
Looking into m_motion.c in the...
The power data of lfclk is measured under the same hardware and software conditions. When we used two model chips, we found a difference of 1 microamps for the value of the...
hi, I am trying to make buttonless dfu working, but I am not sure how to do that. I am using SDK 14.2.0 with nrf52832. right now, the ble dfu example works. and I found in...
hi
i am using nrf52 dk with MPU 9255 as slave.which pin number of nrf52 dk should i use for 4 wire as SDA, ADO, SCL, NCS.In the attached file ,it is given as p0.20(MOSI...
I'm developing custom PCB with the nRF52832, and I would like to use the ITM for debugging. I don't have a J-trace or equivalent hardware, so everything will have to be done...
I was reading the tutorial :
https://devzone.nordicsemi.com/b/blog/posts/bluetooth-smart-and-the-nordics-softdevices-part-1
it says about how a ble device can advertise...
In Mesh SDK, there are 3 versions available for s132 softdevice: s132_3.1.0, s132_4.0.4, s132_5.0.0.
The question is, should I always use the latest version available? If...
Before I use 51822QFAC(with 32K RAM)， add I must use 51822QFAA(with 16K RAM)。
I have modify IRAM area，like this
IRAM: 0x20001FE8 0x2018.
and selete device is 51822QFAA...
We are designing the nrf52840 with high voltage mode and both DCDC regulators.
Where can I find the requirements for the external circuitry, like the inductors. For now...
Hi,
1. what the DC2DC switching frequency of nRF52832?
2. at nRF52840 the inductor should be 10uH with tolerance +-10% but for nRF52832 this inductor can be with tolerance...
