Dear customer,
You can connect to PC serial port directly first. Use some serial tools to check the GPS Bee is work or not.
Because it must receive the satellite signals. So if indoor could not success.
However we are not sure with MAX232 to use with.
So perhaps you should view our GPSBEE wiki to know not only TX,RX work with it. There are some other pins like 15 TP Configurable Pulse output (default 1Hz, max 4Hz) you should use.
Hope can help you.
Best regards,
Yuri
