Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
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...
The firmware used operate properly in the past, but it no longer does after we replaced the MCU(nrf52832).
During SOFTDEVICE_HANDLER_INIT, the MCU is stopped.
The previous...
I am working on a peripheral. This peripheral is IO display only. On the other side, the central is keyboard + display. I have a single, custom service with a single characteristic...

I had purchased the Red Bear Labs "Micro" board to develop code using their MK20 USB Dongle and Arduino.
If I "hack" the programming cable to emulate the "Micro" daughter...
Hi ,
I have recently bought a nRF5232 PCA10040 development kit and i am trying to interface nRf52832 development kit(Master) with AS3955(slave) over twi. I tested the twi_scanner...
Hi all
I'm trying to build a generator based on NRF52832. Outpit signals are: 8MHz clock and two latches signals highly sinchronized with clock - RGB_LAT and TXT_LAT. For...
Hello,
I have a question on how to calculate the capacitance based on oscillator relaxation for NRF52. For example, in the Csense_drv example, when pin is touched by finger...
Hi,
I have a working scanner and manage to require timeslots with the below timings.
Interval 300ms, scan window 50ms, Timeslot length 10ms.
But when i try to...
Hi,
