My sensor is off-standard,so I have to use gpio to read and write my sensor.
Gpio IIC will take about 0.5ms to get data.
My app need send data every 7.5ms,it seems that...
Hi,
My android Proximity application fails on service discovery only for the very first time it connects with the devices(nrf51822 evaluation kit with sdk 5.2.0). Actually...
Has anyone converted the app note AN34 DTM Python script to C# or C/C++ ?
The Python DTM script is works OK with the setup specified in the app note AN34 figure 2, which...
Hi,
I have a serious problem, when I use uart of NRF51822 QFAAC0 to receive data from another MCU, I found that it will lost one bit at same position everytime. my SDK is...
Hi,
I just started to interface the lcd display with nrf51822 evaluation board. The display i'm using is, spi compatible, 18" tft (160x130) from tiny lcd. I took spi master...
Hi,
We are using the nRF905 device in an application where it needs to switch between auto-retransmitting and sending single packets, due to it communicating with several...
I have an application based on the ble_HID_keyboard_template (uses STM32F072 instead of Arduino). The first time I pair my iPhone 5 (iOS 8.1.1) with the nRF8001, everything...
Hi,
I'm using nRF51422 with S310 and ble_app_hrs example application.
Thus I can simulate a Heart Rate Sensor with the board and get data on an Android phone with the...
Hi all! May I use another quartz instead of 16 MHz? Will the output frequency equal to 2.4GHz/16, if I will be use the 1 MHz quartz? Or IC will not work? Is it possible to...
I need to evaluate the real consumption of current for BLE events on RF81822. The HFCLK is 16MHz and the 32kHz clock is external.

Hi, I have two different types of nRF24L01+ modules, both behave differently.
The "troublesome" module always has TX_DS asserted after a transmit, which is the same behavior...
Hi,
I am using the SPI Master 1 to control an EEPROM. I used the spi_example project to help get the code working. It all works fine if the code that initiates the SPI...
We have designed a differential antenna for the nRF51822 CEAA chip.
Each of the RF output connects through a matching circuit to each one of the two 50-ohm to ground end...
How to setup MQTT for CloudMQTT? I have working raspberry PI I can ping and connect to device when follow the user guide. Now I like to try MQTT example but don´t know how...
Is there a list of every interrupt these functions effect. Specifically I am worried about
static void ble_evt_dispatch(ble_evt_t * p_ble_evt)
My assumption is that...
Is there any S110 demo with good communication between periphera and APP in phone side in SDK 6.0? It means that data channle works well from 51822 to APP and APP to 51822...
