to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
Hi,
We are doing DFU updates through a nrf51422 dongle (data passing from UART to BLE), using our own code, based on the multilink central example.
The DFU peripherals...
Hi, I'm have a question :
If i download s120 or s130 softdevice, which SDK version i need to download ?
Which version is compatible with my nrf51822xaa ?
The reason is...
Our BLE hardware is designed to send data at 50 Hz speed continuously using nrf51822.
It worked well with APP with Android 4.3 and some Android 5.0/6.0 ,we can receive data...
Hi,
I'm getting familiar with my nRF52 DK (PCA 10040).
I stumbled on something when I was doing an application that toggles LED1 on every TIMER0 event (200ms). Here...
Hi,
Id like to understand the FDS state after flashing the device. Im trying to check if the record exists then I use it, otherwise I write a valid info into the record....
Hello All
Could you please guide me. i want implement BLE with SPI interface...if i sent any command via mobile Bluetooth..then NRF51 DK should receive the Command and...
I have already changed the define NRF52, NRF52832_XXAA,BOARD_PCA10040 to NRF51,NRF51822 and BOARD_PCA10001 and adjusted the ROM and RAM areas as below.
But there...

It looks like there is a new version of nRF Sniffer for the nRF52, but it doesn't seem to be formally released, although it seems to be 6 months old. Is it expected to be...
Hi,
i was just wondering as we dont need the high clock rate whether its possible to run the nrf52832 with less than 64 Mhz by replacing the 32 mhz crystal with a different...
