Hi,
To use bidirectional continuous scanning mode in ANT, I have to transmit Extended Broadcast/Acknowledged/Burst messages using ANT Msgs 0x5D, 0x5E, and 0x5F (ANT Message...
We are preparing to get BT qualification for our product, developed with the 6 stack now, however want to update to 7 when it is finally released. A comment from the testing...
What is the best way to minimize transfer in progress errors when trying to send ANT messages? I am using the S310 stack on an nRF51422. I have a busy ANT channel that is...
I'm running into a weird timing issue with a nRF24L01+ which I'm not quite sure how to work around in the general case. The basic setup is two radios, A and B. Auto acknowledgement...
I am using mbed library to get leg up on development.
This is the first time I am writing any MCU application and it sure makes things a lot easier.
I am using nRF51822...
I've recently began experimenting with the HID service and connecting to iOS devices in order to achieve lower connection intervals with Apple products (as described in their...
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".

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...
Hi,
I'm trying to interface SIM808 with nrf51822 over uart using nrf_drv_uart. Everything works well for some time, but then uart starts reporting error code 1, NRF_UART_ERROR_PARITY_MASK...
