Thank you, I had a friend with much more knowledge of these components take a look at the chip and he said that since the pin is bent under the chip it was probably still making contact with the socket. The module was working without any problems, so that is a relief.
My next question is regarding the documentation for this module. It says that if I plan on switching from an MN/BL32xx to a MN/BL30xx, I need to change a pair of jumpers. My module does not have those jumpers. Does this mean that my module is incompatible with the MN 3005 chip If so, is there a way to modify the module so that I can switch back and forth between my BL3207 and the MN3005, I also have an MN3206 which also works without any problems.
Thanks again.
