Hi all. I bought a gsm and bluetooth mopdule for my alarm system KIRBIN from aliexpres . The module alarm had a ec200u-cn processor. I’m from Romania and i tried to make it work, with 3 different opperators sim cards but i don;t have any signal for GSM and GPRS too. I saw it exists a ec200u-eu witch look the same as mine.
Here is a picture with my module (i can not upload here because i’m new):
PLEASE if anybody cand help me with some adice for this:
can i update firmware of my ec200u-cn with a EU model to mek it works in Europe/ Romania?
if first option not work, can i replace on the board the CN with EU model?
Sincerly i tried to work with kirbin seller from aliexpress but it is a thief , it sell the product and he knew it not work in other country , and not respond. He is a liar. NOT BY FROM KIRBIN!
Hi @tao13
Sorry for your experience, the CN version of the module cannot be upgraded to the EU firmware, there are some hardware differences between them.
