Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...

Hi,
I try blinky with softdevice example and reconfigure it to support nRF51822AA. I can program my custom board, I can debug as well, but led is not blinking. I have connected...
Hi,
I want to set the advertising interval to 10.24 sec.
I changed the value of APP_ADV_INTERVAL to 0x4000.
But when i try to discover my device using MCP, it is not...
I'm trying to track down an intermittent bug in programming our Nordic board. So, I'm having to laboriously reconstruct the SWD transactions and understand them.
A transaction...
I use nRF51822 Model in my project that I need to run bluetooth advertising all time. And when I measured current, I found 1mA that is not enough to run for 1 year by just...
Hi,
My project include two MCU with n51822 and STM32. I expect upgrading STM32 application firmware by n51822 DFU function. Do you give your advice to implement it by modifying...

Hello,
Is there any delay between when the reset pin is driven low and the actual reset of the chip. Would it be possible to sense the reset pin and perform some quick...
I am designing an nrf52 based device running at 1.8V. To debug the device I was planning to use debug out option of the nrf52 preview DK. However, I just find that, the debug...
I'm trying to follow the code from one of your examples, specifically ble_beacon in SDK 8.0 and eventually I get to a point where I'm not sure what's going on so I figured...
Hello,
I have question. I using examples with nRF51-ble-peripheral-bond-handling with bls_service (PCA10028) and i have problem with unnecessary connection. I want that my...
