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 ;

Hello
I am interfacing between a SPI Master (microcontroller) with a SPI Slave (nRF52832 based chip) and I get the following output on both ends. The transmission seems...
Hi,
I have run into an issue with nrf52840 on pca10056 v1.0.0 board. The softdevice is SD v6.1.0. It seems to be a hardfault which cause a reset when I tried to call sd_flash_write...
Hello,
I need to read resistive sensors values with SAADC. These sensors going throught multiplexer and amplifier. Infortunaly, the signal going into the SAADC is noisy...
There is a race condition in the SAADC driver when using buffer convert.
I am trying to drive ADC at maximum rate to sample 3 ADC channels, and so I call the following in...
Hello,
after I could not use the nRF9160 DK I bought almost a year ago in Germany due to the missing nb-iot coverage I was very curious about the Thingy91 and I assumed...
Sorry for a noob questions but it is essential at this moment as I have not done any development on NordicSemi chips.
What software and hardware tools I need to develop...
Hi,
I am developing a PC SW that connects to nRF52840 device throw a BLE USB dongle(another nRF52840)
How I can tell from PC that a device is connected\disconnected...
Hi,
I use nRF9160 custom board and my application uses USART, ADC, I2c, SPI, RTC and LTE modem. Currently I am trying to reduce sleep current on IDLE state which is 850...
I am going to use nRF52833 chip with SDK v16.0.0 and SoftDevice s140.
There are couple of questions I would like to clarify:
1. Is AoA/AoD direction finding supported...
Hi
Using the nrf52840-dk with SD S140 and nrfx_gpiote, everything runs fund (BLE, TWI etc) but interrup on pin 0,28 causes a Hard Fault. I can not get any sensible logs...
I am trying to modify the existing Thingy-52 code to have a 'new' characteristic. I used the existing Thingy code to 'clone' a new characteristic (a 2nd microphone channel...
Hi
We tested the idle feature(by AT#XSLEEP=0) on nRF9160DK, but no significant change of power consumption before and after enter into IDLE mode, is this result correct...
Hello, I would like to save a log in the nrf5340 FLASH, how many times is possible to write? May I write in the Application CPU Flash from the Network CPU FLASH when the Application...
Hello
I am trying to discover the correct scan interval/window settings to capture the advertized packets from a beacon transmitting every 100ms(10Hz).
Should I just set...
Hello! I've have been designing a custom board. The circuit reads ADC channel 1 for long periods, 1 hour at most. When the reading is high enough it will send an alert using...
