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...

Hello folks
I have a custom PCB board with the attached layout diagram. I also have our firmware that was flashed on to the Nordic beacon kit and tested. I would like to...
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...
I found a strange phenomenon with sdk 8.1.
