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,
I am using the NRF8001 in UART mode and attempting to bond with my android device (Lollipop 5.0 Nexus 6).
i am using the nordic arduino sdk which is found here:...
Hi, I'm using the nRF8001 in an application that requires security so bonds to the remote client/central. My device supports firmware upgrades that may involve new nRF8001...
Hello.
Initially when reading the Gazell documentation I didn't think it'd be a problem but now in Keil seeing this has introduced some doubt whether it's a thing:

Hey.
I am wondering if there is a way to disconnect a slave from a master based on the strength on the connection and not when they naturally loose connection.
To give...
How do I block Bluetooth signals ? (I want the signals to be transmitted 180 degrees, not 360 degrees)
I have read it could be done with aluminium foil, but I have not...
I am looking at using an nRF51 in a BLE product (industrial applications).
One of the things that I have to sort of prove is that it will be a better choice than something...
Hi, everyone. I would like to be notified about the brown-out on my device. I know about POF peripheral, but lowest possible threshold is NRF_POWER_THRESHOLD_V21 (which is...
First off, forgive me for being a newbie at ARM programming in general. In AVR this was straight forward.
I have a circuit connected like this to the ADC (P0.01 = AnalogInput2...
Hi,
I would like to transfer real time ecg data from a 3-channel adc (250 Hz per channel, 16 bits ) using nRF51822 to an android device. I would like to know if this is possible...
