Hi Team,
I was trying dfu to load my application.
Edit #1
I have flashed softdevice.
Then I have compiled the example project 'dfu_dual_bank_ble_s110_pca10028...
I have an external temperature on my nRF51 DK. I would like to read the value of the temperature on my mobile device(Android).
I am able to read the temperature on the...
I would like to use the single shot timer and when the timeout handler is called, I would like to set up the same timer again with different interval this time. Do I have...
There seems to be a discrepancy between the 8.0.0 softdevice release notes and the product compatibility matrix. I would like to know if it is possible to use 8.0.0 softdevice...
Hi,
In my project, I need to periodically perform some jobs on the nRF51822 Beacon kit (sdk 7.1). For that, I think I need to use timers. However, I'm not sure how to do...
Hey everyone.,
I was trying to use nrf51822 as spi slave and just a heads up to know that i use Nrf51822 as master. I see that when chip select CS gets low SPI needs to acquire...
I've added a custom service and a few characteristics on the nRF51822. How can I access the current value stored in one of those characteristic outside of a BLE event occurring...
Hi,
I'm unable to run any application on nrf51 DK (Keil used). When I start debug (no matter what application I load), program always cycles between 2 instructions:
0x000006CC...
Hi,
My application uses the softdevice 110.
Everytime, there is an event on my sensor. The sensor sends the event to my pin, which generates a gpiote interrupt . But, the...
Hi,
I'm trying to determine why a HCI DFU upload fails.
There is a log of the communication below showing the serial request/responses on the Windows side.
Is anyone...
Hi: I use dfu_single_bank_hci to update application. HCI_SLIP_UART_MODE = APP_UART_FLOW_CONTROL_DISABLED, HCI_SLIP_UART_BAUDRATE = 38400.
I use command " E:\hci_dfu_send_hex...
Hello,
In my quest of working with pstorage_raw.c I found an annoying situation when I tried to clear small portions (as I thought by using raw I would have full control...
Hello!
I have based myself on the ble_app_uart example, taken out the UART bit, and all that remains is the bluetooth functionality.
I have also implemented SPI communication...
