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...

Hello,
at the moment I try to add some more services to my BLE device. This goes wrong with err_code = 12 (NRF_ERROR_DATA_SIZE). With some search in the devZone I found...
I have the nrf51822EK and trying to make it report the speed/cadence of a bike. So far the design is to report the speed every 1 second as a BLTE peripheral device automatically...
Hi,
the ANT protocol defines the channel message rate in a range from 0.5Hz to above 200Hz, with the upper limit dependant on the specific implementation.
What are the...
