I am working on a project using a ble nano (nrf51822) using the Nordic SDK 8.1. In the examples I found a way to control an LED using the methods LEDS_ON and LEDS_OFF. I wanted...
Hello,
I am using ble_app_gls example and I have implemented static passkey in the code. Now I want to see if wireshark shows the passkey when I connect to ble devices. For...
Hi Team,
We are implementing an UART communication between a M4 processor (UART master) and a nRF51 (UART slave) and we want to use the UART in Low Power mode with flow...
Hello everybody,
for my project, i will bond the peripherial with the central.
I test my device with the MCP and can connect without problems. When i press the Bond Button...
Hi all,
I am trying to count the positive edges of a 3.5MHz signal with GPIOTE, PPI and the TIMER1. Unfortunately i can only measure to frequencies up to a little more...
Loaded Softdevice S140, ( Using NRF52840 DK board ) using NRFgo Studio.
App flash base is set to 0x00021000 and app RAM base is set to 0x20003000
Looking at the CPU...
In our earlier projects with nRF51 and SDK 8 we used to have bluetooth device names of length 13 or 14 characters. However, when using nRF52 and SDK 12 I noticed that the...
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...
