i can't get GPS data when i try to send it via LoRa

[Mohamedx7]

I'm using TTGO T BEAM V1 board first, when I run GPS code it runs perfectly but when I add LoRa to the code to send to another TTGO T BEAM board it shows 0.00 for both latitude and longitude .... any help??

Please use 3 back ticks wrapping your code.

Like this at the start on a single line: ```c++
at the end of the code block on a new line: ```

thank you for replying to me .... it worked
