BT1038B External Antenna

[Chandler]

Hello,

We are developing a custom board using the BT1038B LE Audio module and have in the design an external antenna connected to pin 51 of the module.

Are there any AT commands to change the module from using the trace antenna on the module itself and to use the external antenna instead?

How does the module select with RF path to use?

Thanks!

Hello!
If you need to use an external antenna, you can choose the "External Antenna" version when purchasing, or contact the customer service of the platform where you bought the module.
