Hi,my friend,
Now,I use nrf905.Situation is as follows:
I use the NRF PCB circuit of data manual.Nrf905 work, often loss of data.
1.The Product host is to use the stick...
Hi,
I want to use the Blend Micro with more security. I want use a passkey for the Bluetooth connection. For example through the iOS Device.
Is it possible? Static passkey...
How do I receive multiple signals simultaneously at a single receiver (433MHz) with multiple transmitters ?
I am working on a polling system. This one is similar to the audience...
Hello,
I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
I am trying to compile nrfutil into a standalone executable, following the instructions at: https://github.com/NordicSemiconductor/pc-nrfutil
This works on Linux, and for...
I am working on a device that contains an nRF52840. It is a BLE central with up to 20 concurrent peripheral devices. For user experience, it's important that it be able to...
In certain situations, I and customer are having issues connecting to cell towers. The issue seems to be most consistent when the Link Monitor indicates a signal strength...
Hi, I was confused about the behavior of GPIOTE Handler module。I defined a handler(gpiote_event_handler) and I hope when the GPIO Pin(0.14) is changed from high to low or...
I use the example usbd_ble_uart with SDK_15.3.0. I need to send any byte received from the terminal via BLE. Do not wait until the buffer is full or the end of line character...
Hi,
I am trying to combine the usbd (hid mouse) example with the uart central example to run on the nRF52840 dongle. I am having a lot of problems and am not really sure...
I have some colleagues that are working on a project where they want to use the nRF52 as a general purpose IO processor alongside providing an BLE interface to a host Linux...
I installed SDK 15.3.0 build 59ac345 and started working though the DFU secure boot loader example. In the 15.3.0 documentation it says
Setup
You can find the source code...
Hello
We are using custom board which has two chip configuration for BLE stack. Main MCU runs the Zephyr Host only BT stack in peripheral mode.This is supposed to be GATT...
I am trying to compile the SPI example in SDK 15.2.0 for nrf52810. I am getting a compiler error in SES on nrfx_uart.c:
I modified the project according to the SDK documentation...
Dear all,
Is this possible to flip a switch on the board to get nRF9160 IOs at 3.3v rather than 1.8v ? I have a LoRa module that requires TTL 3.3v UART signals, and it...
Hello,
I believe I have found a possible race condition in experimental_task_manager / task_manager.c, task_events_wait().
The race occurs if a task calls task_events_wait...
Hello, I'm working with an example of ble_app_uart with SofDev132. I have modified the code a bit but I still use the nrf_pwr_mgmt_run function. The power consumption is 2...
