How to change the bluetooth name？

[zhch_4550981]

If the default bluetooth name of BLE is “ABC”, I want to change it to “123”  through UART or mobile APP, which can be changed for many times. How should I achieve this。

Use Cy_BLE_SetLocalName to set the device local name. Call this API before the advertisement start so that the device advertises with the new name. Also you can use Cy_BLE_GetLocalName to read the local device name.

Thank you very much indeed！

I successfully set the device local name and read it。But when I restart the device， the device local name becomes the original device name！

Hi zhch_4550981​,

So it is. The initialization sequence cannot be changed. You need to store your new name in a nonvolatile memory and then restore it when restart the device. PSoC 6 MCUs have a flash module with one block that can be used for EEPROM emulation for longer retention.

Please see CE195313 for details. Also the BLE_PDL Component uses the same section (cy_em_eeprom section) to store bond data. For more information, refer to the Middleware/Cypress Em_EEPROM Middleware section of the PDL documentation.

Best regards,
