I want to control GPIO toggle by PPI. Timer1 is in timer mode. CC[0] is 1000, and CC[1] is 8000.
I use compare[0] to toggle gpio18 by PPI. I also want to use compare[1] to...
Hi,
I use two evk board to connected and test the uart serialization sample(ble_s110_serialization), one is ble_app_hrs and one is ble_app_connectivity. But I have one...
I am getting get BLE_EVT_USER_MEM_REQUEST and BLE_GAP_EVT_CONN_PARAM_UPDATE event, when writing to ble device, sample code did not handle these event, and seems no document...
Hello:
Why do I erase SDK5.2 version of flash and read not, in SDK4.2 can. I tested nrf51_sdk_v5_2_0_39364\nrf51822\Board\nrf6310\flashwrite_example is a good example.However...
before i write the flash, it has been erased.so ,its value is all 0xff.
when i write 0x00 to flash address 0x0001,the value read out is not 0x00 but 0x01,and the value in...
I'm trying to implement context switching from handler mode to thread mode using PendSV. I set the PendSV pending bit inside an ISR with SCB->ICSR = SCB->ICSR | SCB_ICSR_PENDSVSET_Msk...

I am not sure if this is a limitation with Keil or Nordic SDK. I made another copy of ble_app_uart inside SDK_11 s130 and renamed it with a much longer name. I tested that...
I'm using the nRF SDK5 v11.0.0.
I'm trying to test out UART Logging in the simple blinky example bundled in the SDK.
I added NRF_LOG_INIT() and then a NRF_LOG("Testing\n...
Hello everyone,
I am trying to implement a bootloader to my application to be able to enter in DFU mode.
I am using nrf51822 (32KB ram 256 flash) and s130.
I have taken...
My understanding is that the nRF51 is known to need a fairly stiff external pull-down resistor on SWCLK to avoid noise putting the chip into debug mode. I note that the nRF52...
I'd like to know how to implement a bootloader for the Nordic SoC nRF51822-QFAA-R in order to boot the softdevice and some firwmare. If will be great getting an application...
Does nRF52832 have battery monitor?
I can't find in the datasheet if there is an externarl circuit to monitor the battery. I'm using a CR2032 coin cell battery.

Hi,
I'm developing some firmware that will hopefully run on a few different kinds of nRF52 device.
Is there a way of detecting if the DC-DC converter's inductor/capacitor...
Following situation:
My device acts as central (connecting to ble sensors) and as peripheral (transmitting and receiving data from mobile). Several services (Heart Rate...
Hello,
I followed this tutorial:

Hi guys,
I am using the RFduino nrf51822 chip. I am using the TIMER2 interrupt and it works fine. But when I try to use the BLE along with the timer interrupt both don...
Hi,
I have have one ble project which is using softdevice s110. so that i want to extend this project by adding DFU service to it like shown here
