Hi
My photon has a strange behaviour:
When the photon is unplugged from the power source for a long time (12 hours) and then started again, it’s blinking blue (listening mode). I’m using an external antenna because internal antenna doesnt work. Any advice?
My code:
#include <Wire.h>
#include <Adafruit_SSD1306.h>
#include <Adafruit_GFX.h>
// OLED display TWI address
#define OLED_ADDR 0x3C
Adafruit_SSD1306 display(-1);
#if (SSD1306_LCDHEIGHT != 64)
#error("Height incorrect, please fix Adafruit_SSD1306.h!");
#endif

void isr_rotation () {
if ((millis() - ContactBounceTime) > 15 ) { // debounce the switch contact.
Rotations++;

}
}
When i then try again it’s very often the same but sometimes it’s working fine…
Can I disable listening mode during startup or is there an other solution?
