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
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)

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...
Is it possible for a nrf51822 running s130 to advertise and scan at the same time?
I am trying to scan for other BLE devices using s130 softdevice, but cannot find an example...
Hi,
I have learned that you can change the MAC address on a device by using sd_ble_gap_address_set. However, when I press the sw2 button on the beacon (running a modified...
While reading about setting up nRF51 development environment on OS X , I came across the following:
Unfortunately the only way to erase
the memory is to do some magic...
Hello everyone,
I am trying to communicate among 2 NRF24L01+ modules using 2 ATmega16A microcontrollers.
My SPI communication is working fine as I am able to write and...
I've tried to set up my own BLE project as an exercise in understanding what's going on. It's going okay, with the exception that the device isn't advertising the data that...
I write PWR_UP using SPI and then read the Reg <0>. but I am not getting what I wrote.
Step 1 : Power ON using 3V.
Step 2 : Delay for 1 Sec to get into POWER DOWN MODE...
Hello,
On my custom board, I'm receiving chunks of UART data, without flow control, at 115200bps. Sometimes (its quite frequent now... sometimes after 10 chunks, sometimes...
I'm working on a PC application (using nrf51-ble-driver_win_0.4.1 API) to connect a BLE device and discover BLE services.
Today, I'm tying to connect the Nordic dev kit...
When discovering services using nrf51-ble-driver_win_0.4.1 driver, some ID are received with type BLE_UUID_TYPE_UNKNOWN. So I assume they are 128bits. I then retrieve the...
I downloaded the BLE beacon app S110 v7.1.0 to a nRF51-DK board. The current measurement pins were attached to a 10 Ohm resistor.
I observed the AC-coupled voltage at one...
Hi. We've got a chip with a code QFACA10. I am trying to find out if there is the internal pull-down of SWD line or not. It seemed that adding an external pull-down had positive...
Hi all,
I want to know the effect on power consumption of pins input buffer on and off, does there are big differences between them?
Another question is, since there...
Hey everyone,
