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 looking for a way to use the nordic uart service ( devzone.nordicsemi.com/.../ble_sdk_app_nus_eval.html) from Linux using the native Linux BLE Stack (BlueZ). My application...
by set a char with BLE_GAP_CONN_SEC_MODE_SET_NO_ACCESS, means it can't be read and write, if so, why not remove the char?
any reason behind BLE_GAP_CONN_SEC_MODE_SET_NO_ACCESS...
Is there anyway to limit the number of channels a device is advertising on?
I'm using an nrf51822 with the S110 stack and want to limit my device to a single advertising...
Hi,
We want a throughput between a BLE link 12KBytes/s.
In our application there is a peripheral (in Nordic starter kit), running S110 and we have configured connection...
I have two questions.
Is it possible to use the DAP[n]/DAB[n] registers without using Bluetooth 4.0?
If it is possible, then how? I searched all the sample...
I am starting with Nordic nRF51822 and I would like to know if do you have some samples for use with emIDE (I liked it because you don't have size limitation). And I had some...
I saw two different way to ini ble
1 ) BLE_STACK_HANDLER_INIT
SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, false);
err_code = softdevice_ble_evt_handler_set...
I'm right now getting uC to sleep WHEN THERE ARE NO ACI EVENTS I think I'm doing right, the uC sleeps but I'm not able to wake up despite the fact that RDYN is connceted to...
Hello,
In an ongoing company project we use a couple of nRF51 transceivers forming a beacon enabled wireless sensor network consisting of one base station and multiple...

Hi!
I wonder what is the GPIOs nominal voltage level when I'm using the internal DC/DC converter?
I know that the internal DC/DC converter output voltage is 1,9V but I...
Hello,
we made PCB based on reference with ST balun. In circuit the low freq crystal is optional, so we didnt use it. In software i noticed app_timer use RTC timer. So the...
I am trying to bootload an extremely large hex file using a slightly modified DFU (modified from SDK v5.2.0's example)
The problem is that the hex is so large that eventually...
Im having errors like Arduino is in the while(1) loop if I enable the DC/DC converter in the characteristics and generate service.h file , If I do not use this setting everything...
