Boron no longer connects after firmware update

[X7JAY7X]

I figured it out. I did the following:

In the CLI:

1. Put in DFU mode.
2. Do "particle update"
3. Put in DFU mode.
4. Do "particle flash --usb tinker"
5. Reset

• At this point is should be flashing dark blue (listening mode)

To get it out of listening mode the setup flag needs set:

1. Upload the following program and run:

Argon boots in Listening mode instead to load installed user app

I believe the problem is that the setup complete flag was never set when you set up the device initially, or got cleared. The stop listening command exits listening mode, but does not set the flag, so you go back into listening mode on reboot. The code will manually set the flag in configuration flash. #include "Particle.h" #include "dct.h" SYSTEM_MODE(SEMI_AUTOMATIC); void setup() { // This set the setup done flag on brand new devices so it won't stay in listening mode const uint8…

#include "Particle.h"

#include "dct.h"

SYSTEM_MODE(SEMI_AUTOMATIC);

void setup() {
    // This set the setup done flag on brand new devices so it won't stay in listening mode
    const uint8_t val = 0x01;
    dct_write_app_data(&val, DCT_SETUP_DONE_OFFSET, 1);

    // This is just so you know the operation is complete
    pinMode(D7, OUTPUT);
    digitalWrite(D7, HIGH);

    Particle.connect();
}

void loop() {
}
