Hi,
I want to modify the existing firmware of PT-10 pet tracker from Weiom Corporation, China. It has LPC2148 microcontroller, Sim300 GSM/GPRS module and SiRF III based gps module. But I can not determine the circuit schematic since most of the connections are under Sim300 module.
Do you have schematic of this device? Did anybody tried to modify the firmware of this device before? Or the pins I need to erase the existing firmware and load a new one?
Please help me by sending a schematic of this device or advising how can I do this easily.
Thanks in advance.
