After I get a Disconnected() event, I want to start scanning again, therefore try to call StartDeviceDiscovery() again.
IsDeviceDiscoveryOngoing was checked before.
The...
Hi, I wanted to ask a question regarding sending data.
I currently have external memory that will send out serial data (SPI) to the nordic microcontroller. I have saved...
Recently, I try to programme nRF51822 DK communicating with nRF2401e1 DK,unfortunately，which does not success. With setting radio configuration: TXPower,frequency channel...
Hello
I'm trying to implement whitelist in my code and i found a post which has the following code for the ble_stack_init function:
The ble_app_hids_keyboard example has...
In https://media.digikey.com/pdf/Data%20Sheets/Arduino%20PDFs/A000135_Web.pdf, it says the nRF Beacon app is compatible with nRF51822.
Any reason why it wouldn't work with...
Hi, When I test the SPI with extern flash W25Q64. I found that receive data from W25Q64 is all Zero.
The "blue line" is MISO. The "yellow line" is CLOCK.
According to...
Hello. We evaluate DFU using nRF 52840. After writing sd_s140_bootloader_buttonless_with_setting_page_dfu_secure_ble_debug_without_bonds.hex to nRF 52840-DK, we updated using...
Hello,
I'm playing with nRF52840 on a custom board, trying to connect to the chip via SWD. Segger Flasher is being used, on MacOS. Typically I was able to connect to the...
Hi,
I am having issues to program a NINA B112 using the debug out port on the PCA10040 development board connected with a tag connect 10 pin cable, but when trying to program...
The project is cobbled together, but starts from TWIsensor in the SDK 14 examples. The project is compiled with the gcc toolchain which has not given me any trouble. The project...
I am trying to use UART with interrupts and fifo, by using nRF52 SDK 12.2.0 example. It works until the first overflow, after which I cannot any more receive characacters...
Hi!
I'm using an NRF52 with app_uart. As expected at 115200 baud rate, I occasionally get overflow errors which I can see in my event handler.
However, after these errors...
Hi,
Where are scan requests sent? I'm trying to find the function that does this because I would like to disable it.
I only want to connect with a peripheral based...
Hi everyone:
I am using the NUS (nordic UART service) in my project, and find one problem in this project. The development bench is: SDK13.0, nRF52 DK.
If I build a NUS...
Hi,
I used IOT TCP Server example of nRF5 SDK(Ver.15.0) to complete the communication
between the Raspberry Pi and the PCA10040.
But I found that the communication speed...
Hi,
1. I want to disable MCU UART connection which is SB with GPIO pin 5, 6, 7, 8 and I need to connect that pin on arm based processor so desoldering those short bridge...
Hello,
