有办法在不首先配置模块的情况下访问RN4020和RN48的模块模型名称串吗？

我公司现有的嵌入式板与RN4020已经在外地。我们对性能不满意，遇到了一百万个问题，所以我们决定在所有未来的单元上安装RN871S。因为我们已经在RN4020模块中有了单元，所以我们需要有一种方法来确定我们在我们的主机MCU固件中附加了哪个模块。两个模块都有一个命令（GDM），分别返回模块模型名称，RN4020或RN871.然而，当加电时，如果我们没有使用SS命令明确地请求设备信息服务（RN4020和0x80为RN870的0x800万），则GDM命令返回垃圾。由于SS命令在两个设备之间格式化不同，有没有办法在不首先配置模块的情况下访问RN4020和RN48的模块模型名称串？整个问题是确定我们安装了哪些模块以及如何配置模块（SS、SR、ST命令等）。

    My company has current embedded boards with the RN4020 already out in the field. We were unsatisfied with the performance and ran into a million issues, so we've decided to install RN4871s on all future units. Since we already have units in the field with an RN4020 module, we need to have a way to determine which module we have attached in our host MCU firmware.

There is a command (GDM) for both modules that returns the module model name, either RN4020 or RN4871 respectively. However, when powered up, it seems that the GDM command returns garbage if we haven't used the SS command to explicitly request the device information service (0x80000000 for RN4020 and 0x80 for RN4871). Since the SS commands are formatted differently between the two devices, is there a way to access the module model name string of both the RN4020 and RN4871 without first configuring the module? The whole point is to determine which module we have installed and how to configure the modules (SS, SR, ST commands etc).
