Hi,
I'm using Noble.js on a central RPi3 for DFU updates over BLE. The process is several times slower than doing the DFU over nRF Connect on an Android phone. I believe...
I am designing a NRF52 based device. One of the component , Crystal X1, EPSON FA-128 32.0000MF10Z-AJ3 used in the reference design is not available for purchase in online...
On the included Thing52 example, the LED fires m_ioext_osc_status_change from an interrupt. Eventually, when it comes to requesting use of the TWI this comparison happens...
I've noticed that if I call app_usbd_cdc_acm_write with the length set to any multiple of 64 the data will not show up on my PC until I do another write with a value that...
Hi DevZone,
I am modifying an CAN library for nRF52840 preview DK. In my project, nRF52 preview DK is working as a SPI master and Arduino CAN Bus Shield is working as a...
Hi,
I am developing a device using the PCA10028 Dev Kit
It is configured as a BLE Central, SDK 7.2, SD 120
I am starting out with the example "ble_app_hrs_c_s120_pca10028...
Hello
Ive implemented and modified the light_switch_example and now I want to change the tx_power(sd_ble_gap_tx_power_set(uint8_t role, uint16_t handle, int8_t tx_power...
I am writing a program that waits for button 1 to be pressed. once it is pressed for 5 second it will call the LED ON api and when button 1 is pressed again for single shot...
i want to know which example in the SDK of MESH is the fast way make a demo to show this functon: use our moble phone to control more LED in same time.
remark: every LED...
Hello, I ask a question about power_manager() which is internally called sd_app_evt_wait(). I want the program to enter power_manager () to stop waiting for the event to come...
Hi guys,
we have triggered one interesting state of fds module… This could be somehow connected to https://devzone.nordicsemi.com/f/nordic-q-a/27259/fds-data-corrupted/107629#107629...
I have a problem with upgrading bootloader on NRF52832 IC. We are in the middle of porting our own bootloader from SDK 8.1 to SDK 14, because we had to change BLE modules...
Dear All,
while evaluating low-power options in the context of wireless sensors, I've stumbled upon a strange behavior with the nRF52832 using ESB from SDK 14.2. Here's...
Hi
I modified the SPI master example to read an 16-bit ADC at 44.1 kHz.
While the HAL_TIMER achieves its ~22 microseconds quite good, the SPI driver is quite slow: the...
