My firmware goes into system off state when idle and wakes on GPIO (button input). I want to display an indication to the user for a fixed duration, so I will modify the bootloader...
Hi,
I'm using nRF51822 chip and SDK 12.3.0 library to develop the software. We want to control the motors with PWM. But since PWM consumes a lot of power, we decided to...
Hello.

It takes time for fs_event_handler to be called back after nrf_fstorage_erase is executed. In SDK13.1.0, it didn't take much time, but in SDK15.3.0 takes time to be called...
Hey,
I am using nRF52840-DK and SDK 15.2 and working on 802.15.4. The transmitter is sending beacons at an interval of 2sec. The receiver is scanning the network for beacons...
It seems that the GPS is more inclined to give a fix faster when the trigger defined has type GPS_TRIG_FIX set than if the trigger type is GPS_TRIG_DATA_READY. Is this the...
I am working with a custom board and the nRF52840. I have been able to program various hex files to the Nordic chip on this board using SWD and an official Segger JLink device...
I am using the nRF51822 Development kit USB dongle to try to sniff a BLE connection between two other devices. I have installed Wireshark, flashed the firmware onto the dongle...
Hi,
Couple of questions:
- I'm finding that querying the Modem clock with AT+CCLK? always returns the network time the instant after it has registered with the LTE network...
