As I understand there...
Hi,
I am writing a boot loader which does not need to use the soft device as the image is being transferred over an SPI interface.
I have merged the softdevice and my...
Hi
I suppose that Multiple connection to centrals is available from BT4.1.
Is it possible to realize bu S110?
If it is so, which version is available the specification...
Hello, I made some boards on nrf52832 and I was testing the PCB.

I am writing code that runs on a NRF51822 (to be less specific it runs on a Red Bear Lab BLE Nano). The board has a 32.768khz crystal on it that I want to use to wake up the...
Now I am sending data at 250 ms.
I'd like to send data at 80 ms.
Is this possible?
also,how much can it extend the advertisement interval to the maximum?
thank you in...
i am working with eclipse to program the ble_app_hrs but it is getting error "No rule to make target _build/app_trace.o', needed by nrf52832_xxaa_s132'. Stop" when it builds...
Hi,
In the newer versions of NRF 5 SDK (sdk10 vs sdk12), does the softdevice takes more RAM?
I am using nrf51822 (qfaa) and sdk 12.3. with softdevice s130_2.0.0.1....
