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...
Hello,
I am trying to count pulses on nRF52840 DK's pin for measuring water flow with hall effect sensor. I tried to implement PPI + GPIOTE + TIMER in counter mode, but...
Hi, I am using nrf52840-based custom hardware and have an external flash connected on SPIM3. Till now I was working with my other peripheral connected on different buses and...
Hello Nordic Team
I am using SDK 3.0.1 with a nRF52DK to develop a firmware that can be switched from BLE mode to GAZELL mode and vice versa over a command sent via UART...
Is this even possible? I have a BLE connection with an interval of 7.5 ms. I've set up a radio notification with a distance of 2680us in order to be able to transmit 4 BLE...
Hi,
I want to know how sd_ble_gap_authenticate api works.After executing this api, what are the events invoked at peripheral end. Is there any event that blocks CPU or...
We are designing product based on nrf2401A
The problem that we encountered was that the nrf2401A forgeted configuration data, was it possible ?
we use our product in highly...
Hi,
I am using the nrf51822 in an intermittent high-current application where if the battery is close to dead, will sometimes cause the chip to reset because the voltage...
I am using SDK 8.1.0 and Eclipse on a Mac. I am having difficulty flashing my app that uses the nRF51 sdk onto nRF51. I am using JLink
I assume I need to flash two things...
Hi nrf51 developers,
I'm developing multiprotocol application by combining BLE and a proprietary protocol. I'm using concurrent multiprotocol timeslots API. Started with...
I am new to programming both the nRF518122 as well as the Cortex-m0. As I have been building and running the example apps that come with the nrf51 sdk, I run across the CMSIS...
Hello,
I'm developing device application where I need:
peripheral (advertising also when in connection)
central role
whitelisted connections
maybe some encryption...
Hello,
I'm trying to do some simple printfs to hyerperterminal as a way to debug my code. I have used the uart example init code but nothing prints:
void init_uart(void...
I have enabled data ready interrupt bit and also enabled the fifo bit and also enabled gyro_fifo and accel_fifo bits in mpu6050 so that when data ready interrupt occurs the...
I have a nRF51DK. The Softdevice on the board is S110.
I load the ble_app_template from the SDK 8.1 on the chip. It builds with success. Now with the MCP I am able to see...
I'm now using the lastest SDK 8.1.
I found that if I call app_button_enable() after app_button_disable(), app_button_enable() would not function again.
But if I changed...
Hi all,
I read that the nRF51822 comes as a blank chip from the factory, and this means that we have to program the SoftDevice ourself. I am wondering if this is the only...
