Based on the nRFUart demo, I added a masterEmulator.DiscoverServices() block before the DiscoverPipes() block in a very similar manner. Purposed is to be able to get more...
Hi,
There is much talking about the "large data transfer" over BLE, the l2cap channel being the best option for the moment.
However, does anyone know the datarate achievable...

Can someone tell me how the DETECT signal works in the nRF52840?
This version of the nrf52 has 2 GPIO ports.
Does that mean there are 2 DETECT signals? or is there still...
Hello, I'm using the nrf UART 2.0 app with nrf51822 and I'm wondering how a line of characters is sent using this app. For example if I write 'abcdefg' does the BLE receive...
