Hi all,
I'm using the LE1 to do the mutilceiver,if I donn't use the dynamic payload,I can do it successfully.However,if I use the dynamic payload to do Multiceiver,the...
Hi,
For the LE1,I found that 32.768kHz crystal oscillator need long time(about 350ms) to running,I must do some delay(about 350ms) for the software then use the RTC,or...
In moving to the "rev-2 51422 silicon, we find that the app_timer inevitably fails after minutes to several hours. Power requirement moves from about .002ma to 4.5ma then...
Hi,
I am planning to use an external DCDC to supply the NRF51822 in Low Voltage Mode.
