Ble gps problem

Forte_Koup

I'm trying to make a DIY GPS using the ESP32 DEV KIT and NEO-7M GPS module. Here is the source code I wrote for reference. The connection with RACECHRONO is ok, but 'NO FIX TO SATELLITES' keeps showing up. What should I check?

here is my code :

I've already checked u-center. my gps module keep sending nav-dop, nav-pvt signal

Check the fix type and satellites count

it works using another gps module(m9n). not using neo-7m. m8n, m9n works.
