Hi...
Can anybody help me to run ble_peripheral example (ble_app_hrs for S130). I have build and load the code successfully but cant see the advertisement. But while debugging...
I am working with the nRF8001, and I'd like to create a services.h file that will let me broadcast battery level and as well as allow temperature to be read by a peer.

Hi We have an application where we what to read i2c sensor data over the air to an iPhone. We've taken ble_app_uart_S130 project and grafted in some twi_hardware code. There...
I am interested in the S130 ability to hold 3 central -> peripheral links over BLE, and am looking for some evidence that this has been accomplished with extremely low-power...
I'm trying to implement channel scanning in our nrf24lu1p based USB dongle.
I'm following the specs and basically loop though each channel ;

Hi,
I am using the NRF8001 in UART mode and attempting to bond with my android device (Lollipop 5.0 Nexus 6).
i am using the nordic arduino sdk which is found here:...
Hello,
I want to use the NUS service on my BLE communication. I don't have pins connected for UART, do I need to have them?
When I try to run the device, my program initializes...
hi,
1/ i notice that drivers header files are available in two versions. one inside "components\drivers_nrf" folder and the other inside "components\libraries".
and...
I'm using the nRF51822 DK + SDK10.0.0 + s110. I modified the app_ble_hrs example to send 2x 20B packets of data (via a modified heart_rate_meas_send() function) upon a m_battery_timer_id...
Hi
I have a custom board with no external crystal. Using S130 works fine, but I want to enhance communication with some data being sent over ESB using timeslot API.
...
My English is still poor, but I hope you can understand me.
Press the button to call ble_advertising_start(), which may occasionally restart main.
I set a short timeout...
I am using the FreeRTOS port included in a nRF52832 with nRF5 v11.0.0 + s132. From main() I create a task and I pass it some input data as argument. That data is encapsulated...
Hi,
I am struggling with I2S. While I was debugging my I2S data handler function, I found something interesting. I copy one element from a uint32 buffer into a (static...
Hello all!
Simple question: What is a SNR value for BT LE? I read 20 dB are OK, but I would like some sources/informations to back this number up.
Thanks!
Cheers...
I am using a custom nrf51822 board and S130.
I am trying to pull data from a sensor over SPI and then immediately send that data over SPIS to another processor. Is this...
While trying to implement a simple qdec demo application, I find that QDEC_SAMPLEPER_SAMPLEPER_512us above works ok, yet QDEC_SAMPLEPER_SAMPLEPER_256us does not work at all...
I have a case where I'm using a timer/counter as a counter with one PPI channel routing a GPIO rising edge to the COUNT task. Another GPIO rising event controls the counting...
I have an nRF52 paired to a central device. In order to delete the pairing on the nRF52 I clear the persistent data (dm_init_param_t).
I notice, however, that even though...
Hi all,
I'm a grad student trying to innovate on the BLE concept. I require a continuous signal as a source: preferably unmodulated, but a long duty cycle could also work...
The NRF52 product specification (aka, datasheet) has 3 chapters in it all relating to TWI: TWI (chapter 49), TWIM (chapter 33), and TWIS (chapter 34).
Which section (TWI...
