To be able to upgrade FW through UART, a bootloader for nrf51822 is required in my project. I have tried out the example bootloader in SDK. But this example is using softdevice...
I followed the forum posts and nan-29 to get eclipse 4.3.2 to successfully connect to JLinkGDBServer via a Segger J-Link EDU on Ubuntu Linux.
I can start the GDB server...
I'm using Softedevice 6.0.0 and SDK 5.2. and Keil 4.7.
I Modified bootloader project so it compiles with both ble and hci transports. Currently I use button_0 and button_1...
I am working on the proj that needed 2 MCU and nrf51822 work as slave.
I would like to know any ref on how to firmware upgrade on board without external tool?
We're looking for a Nordic nRF51822 based low profile/small USB dongle that we can use for our iBeacon software.
It would need to come complete with casing and the ability...
Hi all,
i want to establish connection between two threads in cmsis-rtos, can i use

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 I'm learning Zephyr ecosystem in context of using nRF SoCs. How one can achieve current consumption values as low as in datasheet ( 0,4 uA in System Off, with no RAM retention...
After nrf52840 uses the SPIM3 peripheral to send data, turn off the SPIM3 peripheral to enter low power consumption, and there will be 700UA current; if the SPIM3 peripheral...
I am trying to read data from a chip over SPI.
The implementation of the SPI comms is not ideal as they require a new CS/SS line toggle on every byte. I cannot do a bulk...
I hope that someone can show a clear example of this. I surprised that it isn't in the SDK examples. Basically, it is necessary to stop the BLE SD, in most low-power examples...
Hi,
I am having a problem where the client is unable to receive notification from a peripheral after the softdevice in the peripheral returns 0x3002 after a disconnect....
Hi,
I am trying to implement DALI-104 (IEC-62386:104:2019) on top of openThread protocol.
I am using Thread: CoAP Client and Thread: CoAP Server and want to configure...
I am Rattana. I have some project for Bluetooth communicate with mobile phone. Then I will use BC805M(nRF52805).Nomally I connect my MCU with HC06 and I use MCU because I...
Hello I'm now trying to implement the IOS Phones (Central) - Device (Peripheral) liver UART using Multiple Connection - Nordic Uart Service. Devices tried to send a UART signal...
Hi,
We are following the project CHIP and planning on design a matter device with our existing hardware platform. The below are some questions about it:
1. Our platform...
Dear Nordic Bluetooth Experts,
My project is quite simple: A BT Mesh device (generic level server model) powered by a Nordic nRF53832 and an Android app that is used to...
Hi Everyone,
This new way of doing firmware seems to have taken such a turn from what I've been doing for the past 20 years that I don't know where to begin. All I'm trying...
Hello,
I am using android nrf mesh app as a base app and using the latest nrf mesh library version.
I am taking provisioning trails on inline on-off controller.
While...
Hi,
I have used "write_handler(p_ble_evt->evt.gap_evt.conn_handle, p_rtc_service, p_evt_write->data[0]);" to send data to nrf52832 from nrfconnect mobile app but iam able...
Hello,
For our application, we need to form a Zigbee distributed network and not a Zigbee centralized network. That means that routers need to be able to form a new network...
