Unable to connect to BOLT Hotspot for Setup


#1

I have just received the new Bolt and am trying to setup with the iOS app. The app says the blue led should be blinking slowly. It is not. There is quite a complex series of blue led and green led flashes. The SSID Bolt7487223 appears from time to time. If I try to connect with password bolt1234 I get Incorrect Password or Unable to join (the latter I suppose because the SSID has disappeared).

Suspect my board is faulty.

Since I cannot get past this step, I cannot connect to my home network or register the device on the cloud.

Please advise.

Thanks

Pat

This is the chatter that is coming out of the serial port (TX) at 115,200. This is output repeatedly in a loop. Hopefully this enables someone to diagnose what might be going on?

Hi Pat,

The Bolt-IoT customer support team is looking into the matter, and will get in contact with you as soon as possible.

Hi Pat,
In the mean-time you could try using a different power source for the Bolt unit.
Do tell us your experience regarding the same when using a different power source.

Same issue with a wide variety of different power sources, incl 5V and 3.3V.

Thanks

Pat

Any advice please? This device is stuck in a reboot loop still.

Hi @pat.molloy,

I looked through quite a number of forums regarding the same problem on ESP8266.

This problem can have 2 causes.

  1. Incorrect Firmware. I am sure this is not the case, as all Bolt units have the same firmware uploaded. IF the others work, then this one should be fine.
  2. Problems with the power supplies. Now I know that you have tried different power sources for the Bolt unit, but have you tried changing the USB cable that you used?

The problem is definitely in the power supply. So it’s either the supply itself, the usb cable or the Voltage regulator on the Board. (The issue at the Voltage regulator seems unlikely as you have tried 3.3v)

Do check with different usb cables, and different power supplies.

If it still does not work, you will definitely be entitled to a replacement.
