FAQs

I cannot upload sketch to Feather nRF52 !! Although I have followed the tutorial correctly.

This is probably caused by the bootloader version mismatched on your feather and installed BSP. Due to the

difference in flash layout (more details) and Softdevice API (which is bundled with bootloader), sketch built with

void setup() {

pinMode(LED_BUILTIN, OUTPUT);

}

void loop() {

digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)

delay(1000); // wait for a second

digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW

delay(1000); // wait for a second

}
