I got the Dynastream N5 kit and have successfully used it with limited ANT work and was trying to get BLE working but can't get a driver for the USB dongle. On the 51422 product...
Hello. Is it possible for a central device to retrieve the BDADDR( 6 byte array data ) of a past peripheral device by using the peer manager? ("past peripheral device" refers...
Does anyone know how the raw data message is structured to enable GATT Proxy? Here is a screenshot from the app. I know one byte is used to indicate whether to enable or disable...
Hi,
actually I developed a system based on an nRF24AP2 able to read data coming from different HRM ANT+ sensors and transmit them via WiFi using ESP8266 that is acting as...
I have clock drift issue, should I calibrate anything? I test this simple code to get 1second or 100ms signal both of them are inaccurate.
here is my code for 100ms; I tested...
I'm trying a new device based upon the nrf52810 and it won't run past sd_softdevice_enable - it goes to the assembler window and halts. The device does have a 32kHz xtal and...
Hello,
I was reading some SDK 15.3 code, there's something like this:
__STATIC_INLINE void pwr_mgmt_sleep_init(void) { #ifdef SOFTDEVICE_PRESENT ASSERT(current_int_priority_get...
Hi all, I'm developing nRF52840-DK to use it as an central device.
Base example is usbd_ble_uart: I'm going to communicate with peripheral device using BLE, and control...
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.
