Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...

Hello,
Could someone give me a hint with the following problem?
I am using two example projects (ble_app_uart_c, ble_app_hrs) to connect a central and a peripheral.
An...
SDK11, nRF51422.
Is it safe to use pstorage and fstorage at the same time?
I want to use fds for data storage in my firmware, but device_manager_peripheral.c requires...
Hi, I am trying to read a 24-bit register (with 8-bit address) using the I2C (nrf52). And the timing diagram is given below.
Basically I created a 3-element array (24...
I am having trouble getting the experimental ble_app_multirole_lesc example working with Android and nRF Connect. It is working fine in iOS. I am using v12.1.0 of the SDK...

Hi,
I was testing our product with PPK today and noticed one weird problem,- it seems that time is incorrectly displayed in the PPK software. Please have a look on the...
I have customised the ble_app_uart example for my application and the modified code works with the DK board. When I wanted to deploy this to the beacon board (pca20006), I...
I am using the SAADC on a NRF52 to read the battery voltage.
Everthing works fine on the NRF52 DK board but on my custom board I get around
the half of the real voltage...
Hi Nordic Semiconductor's community,
I have a question about the function sd_ble_gatts_value_set(), more precisely about if it is
possible to set the CCCD value of a characteristic...
Hello,
we have developed a custom BLE peripheral device. All peripheral devices have the same name. If we want to indetify a specific peripheral device with a smartphone...
I'm using the nrf52 for providing Bluetooth connectivity to an embedded board. My current perspective is that the nrf52 should physically be connected to the UART pins of...
Hi All
I am porting a small OS to the nRF52832. I want to be able to lock down memory of unpriviledged processes.
I have not integrated the softdevice yet.
The memory...
Hello
where can I find some examples of how to create an Android app with BLE NUS peripheral? I have only found NRF Uart app but there is central mode implemented in this...
HI!,
In Eclipse Neon.1 x86_64 with SDK12 examples I get this error:
Symbol 'NRF_CLOCK_LFCLKSRC' could not be resolved
In this line:

Hello everyone!
I have studied the OpenMesh for a couple of days. It seems the Openmesh framwork is standalone with the ble stack(S110), and the framwork operate the RADIO...
Hi everyone, I am working on an NRF51822 project which requires the use of non-volatile memory to store user profile (so I think either flash or external EEPROM). As far as...
