5th gen. RaZberry - not working with blinking LED's

[yesokyoon]

Hello,

My 5 RaZberry's out of 6 total(Mfg Date 18.02.15 with ZM5202 module and Crystal marked H) I have bought are not working with Expert UI.
BUT they work fine with Sigma Design's Z-Wave PC Controller program.

Here is the story.

1. All of them worked fine out of box. LED's(red and green) blink for 1 second on power up. LED blink once on API reset and frequency change.

2. Successful inclusions and exclusions of switch device with steady on LED.

3. Successful switch device on/off control.

4. After changing frequency between JP/KR/EU RaZberry suddenly begin to blink LED's, and stops working with ip_address:8083 setting.

5. Even with blinking LED's RaZberry works fine with ip_address:8084 setting, including firmware upgrading to v2.0.1-rc15.

6. This is all the same with 5 RaZberry's so far.

7. However, all of them work fine with Sigma Design's Z-Wave PC Controller program.

I am using DC 5V, 2A power supply on RPi b+.

Is there a way to revive faulty RaZberry's, with dev kit from Sigma Designs?
Is there a way to bypass firmware check of RaZberry so that it may work with Expert UI?

Thanks in advance,

Yesok Yoon

Same problem here
Razberry is blinking just after changed the frequency on the panel.

did you solve your hardware?

There is a bug in the firmware - it kills itself after switching to KR frequency. If you have experienced this, you need to send it us for full reflashing. Firmware upgrade thru UART don't work anymore. Apologize for that.

To where should i send the devices? (2)
ps: i'm here in brazil ( got the cards from amazon.com )

The problem is it is too costly sending my units to Europe!

Hello the same thing happened to me.
I change the frequency after that I can no longer use my ZWave.

Someone could fix without having to send for assistance?

Olá Fabioyy também estou no brasil, conseguiu arrumar ?

Apologize for the inconvenience.

The problem was fixed a year ago, means you still have older firmware in your RaZberry.

I really wonder what pushes people to switch to KR frequnecy while they are in US or in Europe...
