I am using the `mcumgr` subsys to enable the DFU (Device Firmware Update) capabilities in a custom device that also features a custom (non mcuboot) bootloader. In order to...
Hi !
I have a peripheral that can connect to other nRF52's or a smart phone such as iPhone or android. Is there an easy way to detect a smart phone?
The best I can think...
Hello Nordic Team,
I have a working project that uses BLE to communicate with a mobile app, and I am now looking to integrate Google Fast Pair as an additional feature....
Hi,
I recently found out about the Periodic interval feature on GRTC CC[0] and it seems like it would be quite useful for my application. Most of my code so far uses the...
Hi,
I have integrated Neuton’s “Transport Type Detection” pre-trained model into my firmware, running on a nRF52840dk. For collecting 9-axis IMU data, I’m using the ST X...
I'm trying to implement a fall detection feature on the headset side using the LSM6DSOX IMU sensor. The IMU is configured successfully, but the board halts after the INT1...
I have a ready hogp struct and I'm trying to subscribe to an input notification (I'm connecting to a bluetooth keyboard) and I'm getting error -22. Here's the callback in...
The spec of nrf52 mentiones 'Propriatary RF' as option. I was wondering if that could be used to implement 802.15.4 which would save us an entire IC and power and like basically...
Hi there!
I would like to implement the nRF24L01-module to one project.
But, it would be great, too, if i can use the application manual to use only the chip itself with...
I have the nRF51-DK development kit (PCA 10028). I'm following the gcc tutorial here - devzone.nordicsemi.com/.../.
I'm using the ble_apps_hrs project as a basis for my...
Is it possible to connect DCC / DEC4 to a transistor to turn on / off a part in my circuit? I assume yes, but I just want to make sure.
Or, is there another way to turn...
Hi again,
If I use BluetoothGATTSetCharacteristicValue and set wr_auth = 1 in the ble characteristics, I receive a BLE_GATTS_EVT_RW_AUTHORIZE_REQUEST event. I can also see...
Dear Nordic developers,
Does TWI supports bit level clock stretching? Means that after each bit (not byte) slave can hold down the clock and master should perform appropriate...
So I have the following bootloader code:
int main() {
uint32_t code;
sd_mbr_command_t mbr_command = { SD_MBR_COMMAND_INIT_SD, };
code = sd_mbr_command(&mbr_command...
My ANT BLE application runs on a custom board with a nRF51422, SD 310 rev 2.0.0
I can use the nRF UART app on an android phone, but on an iPhone with iOS 8.4 I can't even...
Hello,
I'm using an PTR5188 development board for my project which breaks out PIN 26 & 27 for ADC only. I'm using mbed as my development platform and haven't been able to...
Hi there
Can you clarify a point for me?
Quoting from Gazell link layer user guide:
"If only the ACK packet sent from the Host to the Device is lost, but both the initial...
Hello.
Reading the documentation of pstorage_load and the actual implementation has left me with confusion.
The documentation states that the size and offset parameters...
I uses S110 V6.00 softdeivce ,v5.20 SDK, and the nrf51822QFAC chip.
now I use the 32k ram ,but it is wrong.The program is not run.
I only use the 16k ram ,as same as nrf51822QFAA...
Hello everybody,
I'm trying to make TIMER1 working on nRF51822 together with softdevice.
In particular I would like to drive an interrupt line that goes to another microcontroller...
Let me ask you a communication sequence between nRF51822 and peripherals.We assume 5 peripherals.
In a sample program for multilink, original sequence is that 5 times repetition...
I'm trying to have an nrf51422 using S210 go to sleep and wait until it gets a signal from another ANT device to wake up. The other ANT device (master) will not always be...
