Hi, i have a NRF51-DK (nRF51822 - PCA10028) board and using SDKv10 with SoftDevice S110.
I read everything i could find about this topic and i see people claiming data rate...
I am looking to synchronize collecting of data from outside devices with the connection interval of the nRF51822 and the S110 vers. 8.0 softdevice. Are there specific events...
I want to send big amount of data (10kb) with characteristic of 16 bytes. when the phone side is subscribed to notification I run a loop of data sending.
how can I synchronize...
I have read through the forum on this and I am still not completely clear. Here are my questions:
Can I create characteristics that are larger than 20 bytes? The Bluetooth...
In looking at the nRF51 UART Example I'm wondering about data loss over the Bluetooth interface.
When bytes are sent to the host, is there a re-transmission mechanism somewhere...
Hello,

Hi there,
is it possible to share the nrf51 reference layout as p-cad files so they can be (easily) imported into circuit maker / kicad?
I think this would be interesting...
