I am trying to create an nRF8001 based application that will broadcast battery levels (pipes broadcast, set), and give out temperature data (pipe indicate - TX_ACK) to connected...
Hi,
I'm using redbearlab's nrf51822 board. It is a arduino compatible board and hence it is using 0,1 (mapped to 9 and 11 for nrf51822). How do I make printf print to this...
An external PA/LNA is used to extend range of nRF51822, and S110 is used for BLE, How to switch between PA and LNA? and how to disable PA/LNA when there isn't transceiving...
Hi...
Can anybody help me to run ble_peripheral example (ble_app_hrs for S130). I have build and load the code successfully but cant see the advertisement. But while debugging...
I am working with the nRF8001, and I'd like to create a services.h file that will let me broadcast battery level and as well as allow temperature to be read by a peer.

Hi We have an application where we what to read i2c sensor data over the air to an iPhone. We've taken ble_app_uart_S130 project and grafted in some twi_hardware code. There...
I am interested in the S130 ability to hold 3 central -> peripheral links over BLE, and am looking for some evidence that this has been accomplished with extremely low-power...
Hi all, i am experimenting on the example "ble_app_beacon" on my smart beacon kit, but i have two questions about it (though they are pretty general):
When a connection...
Hi Experts，
I use TIMER_1 and PPI to driver a 'H' style bridge for our motor. Unexpected system reset will happen if I trigger the 'H' bridge PWM with ble connected. It...
Hi,
I run the code of the radio_test example in a VisualGDB project. When I start it with a debugger connected, VisualGDB informs me that a ARM semihosting system call...
Hi, is their any brief explanation for nrf5-sdk-for-eddystone project firmware newly released by nordic. I go through the project but it is very hard to understand can any...
We have an use case that we may need to support up to ,say 500 sensor nodes and it may be added or removed dynamically. And we should collect all sensor data within 3 seconds...
Hi all:
Based the descriptions in data sheet, the GPIO9 and 10 are set to NFC antenna pins by default.
And I cannot control these 2 pin correctly by configuring the pins...
I want to use NRF51822 to advertise is door close/open. No need bidirectional data sending.
Only one way from NRF sensor to mobile phone app.
Actually I have only two different...
I am using NRF52 S132, and using UART service , but my phone is getting disconnected automatically after 1 or two minutes. I have seen this question asked in Forum but that...
Hi,
Has anyone test with Nexus 5X ?
I could not change connection interval 7.5ms, the interval is always 45ms.
