Hi all,
i want to establish connection between two threads in cmsis-rtos, can i use
1) semaphore to do this?
2)message queue should be used or any other ipcs can be...
Hi,
I have two CPU in our product. (STM32F2 and Nordic nrf51422).
I use serialization function to link those two CPU(refer to ble_s110_serialization sample)
But I find...
Hi,
My behavior is as follows
Turn on my device(use 51422) and advertising(2 Service and 3 Characteristic)
Turn on my cell phone(Samsung Note3),scan my device...
Hello:
I used analog IIC write MPU6050. Again after power download programs, mpu6050 can run up there ACK response. But the debug will not run. Simulation IIC because no...
Hello!
How can I communicate with my nRF24L01+ and nRF51822 at the same time. I can set up same channel, CRC-mode and I don't use ESB. But what about address? How do I set...
We recently announced that we now support “extended industrial temperature range” (-40 – 105C) on our nRF51822.
The devices supporting -40 - 105C are the QFAA (QFN with 256kB flash and 16kB RAM) and the…
Introduction
Using proprietary protocols can be an effective way of addressing shortcomings in BLE. When communicating between two nRF chips, one can for example use a different packet format or different…
Hello everybody,
I have just published the sourcecode of FruityMesh on GitHub. It is a meshing algorithm that uses standard BLE connections. Plug in as many nodes as you like and they will automatically…
We have produced a video tutorial in two parts about Bluetooth low energy. The purpose is to give you a developer’s introduction to BLE and the development tools offered by Nordic Semiconductor.
NB! Please…
Introduction
In a variety of use cases there is a need to share a common clock among multiple devices. Such a common clock can be used for many purposes, for example by having each node in a network perform…
When designing a high-frequency PCB there are some rules that should be followed in order to get a good working radio/system. Below are some general PCB guidelines. These guidelines should be followed…
