I’ve got a bit of a hardware issue with the nRF52811 UART, receiving DMX data from a Chinese DMX controller.
Standard DMX data-rate is 250Kb/S, so the minimum bit time is...
Hi,
I am using the Nordic UART Service (NUS) peripheral and central on two nRF52840 DKs and I am developing with nRF Connect SDK v3.0.0 .
I can't manage to increase the...
I am getting an occasional softdevice assert on a BLE central device (hub). Both the central and peripheral devices are nRF52840 using Coded PHY and NCS v2.7.0. This error...
I am trying to keep nRF5340 in sleep state, and wake it up when there's a user input (e.g., button) and send a packet as fast as possible to iOS18. What would be the latency...

Hi, even if I set hal_nrf_enable_ack_payload(false) on the sender (and receiver), the receiver still sends back an ACK which i can detect in the NRF_ISR(). is this normal...
Hello,
I have a pca10028 and I am wondering if I can use it also to flash nrf52 boards.
I quickly tried with rknrfgo on mac to wipe a custom board based on nRF52832 and...
Hello.
I decided to use an external solution for RTC.
Sometimes the RTC chip offers an buffered 32.768KHz output.
Can I use this output to supply the 32.768KHz to the nRF52832...

Hi all,
I am trying to count the positive edges of a 3.5MHz signal with GPIOTE, PPI and the TIMER1. Unfortunately i can only measure to frequencies up to a little more...
Hai
i am using mbed to program my nrf5188. now i am using securityManager to implement a bonding between central and peripheral. now i need to know when a device is connected...
Hi,
In my code, I have not started the HF clock. I call the ble_stack_init where "SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, NULL);" is called. Which HF clock...
Hi, all.
I tested ble_app_uart in example directory by PCA10040 board.
The ble_app_uart includes "printf("\r\nUART Start!\r\n");" and "UART Start!" cames out on the putty...
I have a scenario where I have multiple peripherals (nRF52) and multiple centrals (cell phone).
The user is going to use only one central with only one peripheral together...
Hello
In case a connection is disconnected locally by calling sd_ble_gap_disconnect(), no BLE_GAP_EVT_DISCONNECTED is fired even though the sd_ble_gap_disconnect() function...
Hello, I'm trying to optimize power on HID Keyboard app.
This post was helpfull but yet some questions remains.
If I use several services, and want central to be abble...
After S110 7.1 ble_stack_init(), any read/write to temperature register cause a HardFault.
Some sentences like:
