Hello

Some questions:

1. Is it possible to get acces to the CH9141 firmware update application ?

2. The IOS BleUART demo application. Is there a version based IOS Swift language ?

3. The Android BleUart demo application. What development environment is supported ?
   

Thanks in advance.

你好，目前最新的9141固件版本是3.6的，可以AT指令：AT+VER  查看版本号，如果不是最新的，可以发送邮件至邮箱：lpc@wch.cn，我们这里可以提供上位机更新。
