When using app_timer through scheduler, a break and go will overflow the event queue if a timer is a repeat timer. The effect is that it's not possible to debug.
To work...
I need to be able to actively set the value being incremented in the Timer2 register on the nrf52 (what I believe would be it's main register). It seems that this might be...
The errata for the nRF52 indicates higher consumption in managing timers and GPIOTE. Does the BSP for SDK11 follow recommended practice to deal with these errata can I ask...
Hi,
I am trying to understand the pstorage to record a log for temperature. In my code, I can call pstorage_init(), and clear a block but when I try to store some data...
I would like to source a compact BLE board to act as a lock controller developed with with a matching transceiver for use in a fob and an app.
It would toggle the pio and...
Ok so here is the issue. I was trying to build a simple application which is described in the tutorial for characters. After building an advertisement and understanding the...
I was working with IAR and SDK10.0 before. For some reason I have to transfer my project to Keil and SDK9.0. My program worked well for the old settings. While keeps got NRF_ERROR_SOC_NVIC_INTERRUPT_NOT_AVAILABLE...
We have a product that uses the nRF52840. We have seen that very rarely, unexpected resets happen with the reason being OFF. We have yet to encounter this issue in a lab setting...
I'm using the SPI manager to talk to an ILI9342 graphics IC. I need to toggle an IO line during a transaction or in between transfers. For the first byte the line will be...
I am trying to enable DFU over USB with the nRF52480, while keeping the possibility for Serial communication. I got a working example with both separate, however when I try...
It's my mistakes.
1.I want to measure temperature from DS18B20,but I don't confirm the capable of the pin - P0.05.Because it's Analog ，but DS18B20 is Digital.
2.I set the...
Hello, I'm getting started with a nRF52832, I've got the SDK 16.0 installed and what I think are all the latest packs installed. I try to build the examples\ble_peripheral...
Hello everyone.
I'm trying out the "Zigbee Multi Sensor Example". infocenter.nordicsemi.com/.../zigbee_multi_sensor_example.html
I have 2 nRF52840 devices.
I wrote the...
When my program starts, I set up a watchdog timer for 100 milliseconds and I start a repeated app timer that runs every 90 milliseconds to feed the watchdog. I use the app...
I'm trying to send data via UART from a NUCLEO-F401RE to the nRF 52840 DK. But the data I send is not comming through correctly. For example when I send 3 the nRF prints 32...
I have an existing product to which I need to add SPI to get Wifi compatibility. Basically the Nrf52 is acting as central and passes BLE events on to an ESP32 with Arduino...
Hi.
I have nrf52840-dk board. i tried the UART example from the peripherals directory. it works with the default, if i open a console on /dev/ttyACM0 and on /dev/ttyUSB0...
Wanted to ask if there is any example on configuring the GPS into single shot mode.
I know the asset tracker can operate in continuous_mode and continuous_power_saving_mode...
I am attempting to use SDK15 with the nrf52832 to communicate with multiple sensors over I2C. However, in the twi_sensor and twi_master_using_nrf_twi_mngr examples, as well...
I am using the nRF52840 with the SoftDevice disabled to run a proprietary RF protocol. For much of the time, I have the radio in continuous receive mode by making use of the...
I have a nrf52 application that samples four saadc channels at 1kHZ. That is: Map four pins to ADC input and let Easy DMA take care of the sampling so that the data is processed...
Hi,
I have measured QSPI current consumption on our product at no access period, and got 1mA (too high current!).
So I tried to check with nRF52840 DK to confirm our...
