I want to count clocks in order to implement a watch. I use the RTC0 as my time-base and count mainly with this device. As it has just 24 bits it would not last for long,...
Hi,
how long does it take time if i would wake up a nrf51422 rev2 (ANT and BLE) in deepest possible sleep mode ?
And how long does it tai if after wakeup it had to communicate...
I saw that the app_timer uses the SWI0. Could you explain what it does and what the advantage is compared to "timer_list_handler_sched()" calling "timer_list_handler()" directly...

Hello,
Has someone been able to use DFU with nRF52 device?
I'm trying to add the DFU capability/service to the HRM example.
I have added the BLE_DFU_APP_SUPPORT define...
maybe the document of GPIO Pin sensing mechanism has some wrong in the nRF51 Series Reference Manual (version 1.1).
sense high/low level defined in the document is different...
Hello,

Hi,
I can't find any data on the analog comparator delay in the datasheet. Except the 15 us for anadetect signal. Is this the delay through the comparator for normal signals...
Hi,
I am developing some DFU OTA firmware for nRF51822, QFAAH0 (v3 silicon, 256kB ROM, 16kB flash), on a custom board, using SD110v8. Both my application and bootloader...
I am playing with the nRF52-DK preview and I noticed the samples in the 0.9 SDK are set to 32k of RAM. I increased it to 64k as per the chip specification and had no problems...
Hi,
I'm in a situation where I need to get two devices communicating using S110. I am aware that I can send using S110 and I am only referring to small transfer sizes....
Hi,
I meet a very strange situation when I tried to wake up nRF8001 from sleep.
I send 0x05 to nRF8001, it replies me ACI command 0x40 is unkown (0x82).
I have checked...
Greetings,
I recently bought an nRF51 dk and was trying to see how to implement the AVRCP profile to play/pause music on a smartphone.
After some research, am i correct...
I measured the conducted power on the PCA10028 demo board and get ~2dBm out when I set the output power to +4dBm. It appears the PCA10028 is using a discrete balun. Is 2dB...
