I have been trying to understand and get the “ble_app_template” running this weekend, but I keep running into errors. For example in
static void sys_evt_dispatch(uint32_t...
Based on the nRFUart demo, I added a masterEmulator.DiscoverServices() block before the DiscoverPipes() block in a very similar manner. Purposed is to be able to get more...
Hi,
There is much talking about the "large data transfer" over BLE, the l2cap channel being the best option for the moment.
However, does anyone know the datarate achievable...
NRF24AP2 with MSp430F149 . ASYNC 9600 N 8 1
step 1 : reset NRF24AP2 with reset pin , and received a pulsing signal through RTS pin
step 2: send a char (0x4A) to NRF24AP2...
Hi guys,
I am using the gcc setup to program my boards. However for flashing the softdevice I use nrfgoStudio. SO I downloaded the hex file and fashed the siftdevice. But...
How do you create hid information for a joystick and send it over BLE. Nordic doesn't seem to have
primitives for this (they have keyboard and mouse facilities). I'm working...
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...
Hello,
I am working with the GPIOTE library to get a GPIOTE_IRQ from a peripheral.
I have several questions regarding the library and how IRQ works.
1.How do I clear...
Hello,
I am using SDK7.1.0 for NRF51822.
In my subroutine, I would like to disconnect with the peer device, and re-advertise. But when after re-advertising, I found the...
Is it possible to set scope for search in info-center only for SDK 11? It search in all SDK versions and sorts results randomly. It is very annoying. Especially when there...
Hi,
I want to build expertise in BLE and want to use the Nordic nRF51x22 to build a hardware and write the firmware for the same.
I am planning to use the nRF51 DK....
I'm calling sd_ble_gatts_characteristic_add multiple times to add characteristics to a peripheral. At some point I get a return value of 0x200020B6. I'm not making much headway...
