I am using the L89-HA GPS module in the custom PCB. I am getting GPS data, but the module is not responding to any command i.e Hot start , cold start etc. Do i need to update the firmware of the module?

HIi @mohamad.firdaus, with few debugging the module is responding to the command i.e through isolated testing of the module … the issue was probably the soldering joint issue..
