Hi,
I would like read a long characteristic.
I know that I have to use sd_ble_gattc_read and I have to multiple call this function.
But I don't know where I have to call...
Hello,
I want to implement some kind of control point. This means, that I want to handle BLE write events to some characteristic. I've seen that the payload of the ATT...
Hi,
i tried to find an example with SPI which describes the connection between two nrf24LE1, one as master and one as slave, but i could not find anything. I need the following...
