Hello,
I have a design with the old Bluetooth module WLS123A1M and I try to change it with the new Bluetooth module 800133001. What should I change because the new module never answer to my AT commands (the AT commands with the old module work fine)?
Best regards
Serge

Best Regards!

Hi Serge,

The old Bluetooth module is different from the new one, and you need to use different AT commands with the new one. Please visit AT Commands of Serial port bluetooth module (Master/Slave).
