Hi, Nordic I see two interrupts:
#define USB_WU_ISR() void usb_wu_isr(void) interrupt INTERRUPT_USB_WU // USB wakeup interrupt (0x5b) #define WU_ISR() void wu_isr(void) interrupt INTERRUPT_WU // Internal wakeup interrupt (0x6b)
maybe WU_ISR() is one function USB Dongle auto resume itselft, now I ... (more)

I am looking to test the performance (range, data throughput, packet drop rate etc.) of BT5 in application specific setting using nRF52840. Ideally this would be done by establishing BT5 connection between two PCs, which would be used to ... (more)
Hi, I'm trying to create a custom PCB that uses nRF52832-QFAA and a Meandered trace antenna.
The PCB's environments are 4 layered, FR4, 1.6mm thick, and green PSR ink.
Thanks to Bjørn Spockeli's answer, I was ... (more)
I want to setup pairs of nRF51-dongle and nRF51-beacon where dongle-1 will always bond with beacon-1, dongle-2 with beacon-2, etc. If dongle-1 and beacon-2 are switched on while beacon-1 is still off, dongle-1 must not bond with beacon-2.
I'm ... (more)
Hello, I need HID device with NRF51 Dongle. when NRF51 Dongle insert PC, PC will check it as HID device. So, could anybody can share suggestion how to add HID on NRF51 Dongle?
Dear Now, I need make one nrf52832 board as USB Dongle, it can be HID device by checked from PC. And, nrf52832 should support esb protocol, now for esb, I know something. But how to make nrf52832 board as USB ... (more)
I have two nrF51 dongles and I am really interested in making the pairing of both of them using the proximity search feature of ANT. So far what I did is, I took the broadcast example and converted ... (more)
Hi. I have two nrf51 dongles that communicate with each other. When I set the transmission power to -30 dB, the range is almost like 15cm, but whe I set it to -20 dB, it has a range upto, say ... (more)
I want to start developing a Bluetooth device with the NRF52 DK. For debugging and sniffing purposes to see what is going over the air, use the NRF51 dongle, get a NRF51 DK or a second NRF52 DK ? What is ... (more)
I need to develop PC software to Discover, Connect, Get and Set data to the nrf device that we developed.

Hi, I just purchased an nRF51 sniffer. I have set everything up as per the UM. When I invoke the sniffer application, it says scanning for devices, but nothing shows up. I searched thru the archives to see if anyone ... (more)
I'm using the nRF Dongle for sniffing. Apparently there are many problems with the sniffer application.
First of all, the CTRL+R command for downloading the FW did not work. I had to install the HEX manually (apparently ... (more)
I tried to get the ble_app_proximity example to work today, with either the nRF51-DK, nRF51-Dongle or nRF52-DK, along with the Nordic Connect app on Android.
I encounter the following issues:

Hi Nordic, I am using PCA10000 v2.2.0 with MCP and FW "MEFW nRF51822 0.11.0"
I just tried the "nRF Connect" under Windows 10 and fail to use it. Below is my steps:
Does anyone know the dimensions of the NRF51 dongle? I'm seeing 16mm x 28mm here but that doesn't seem right (might be the dimensions without the USB connector portion).
I am writing an App for the Central/Master side using the s130 v1.0.0 SD. I am connecting to the soft device using the python wrappers for the nRF51-BLE-Driver-Win 0.5.0.
