Hi,
While the softdevice is active (nRF51822) available interrupt priorities are:
typedef enum {
NRF_APP_PRIORITY_HIGH = 1,
NRF_APP_PRIORITY_LOW = 3
} nrf_app_irq_priority_t;...
Hi all,
I'm trying to use NRF24L01, using REUSE_TX_PL command,
the data sheet says as long as CE keep high, the chip will transmit the payload continuously, what i wondering...
Hi
Did you have tested the power current of nRF24LU1 when RF was off and USB worked normally?
We want it less than 4mA. Could you have any idea to make it? Thanks.
Hello! I am trying to develop on the nRF51822 eval board as called PCA10001. The programming interface I use is uVision4 on win7.
I would set a static PASSKEY for the pairing...

Hi,
I'd like to add some custom data (25 octets) to the nRF8002 advertisement packets, using the vendor specific data type (FF).
Is this possible in some way or do we...
Hi, I am trying to enabling a notification of an attribute(once the attribute changed, the server will push the new value to the client) and I learned I have to first configure...
What's the proper way to implement bonding that depends on proximity (rather than a whitelist)? So when the client (phone) is close (say, five to ten centimeters) to the server...
