In order to get more details, I am currently working on integrating the Android...
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 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...
