I would need electronics and communication interface specification for the connectors under the covers in 9100i, and same interface somewhere under covers of 6100i. We are ok to remove the wifi module as the wifi without api support is useless. However, developing such interface would be very difficult without any interface specifications. Apparently the interface is a serial bus, but protocol specification and serial port piout would be necessary. The current wifi module does not seem to respond to any port, so it is only connecting out.
