Data reception and transmission system between LoRa E32 and LoRa Ra-02
问题
我想创建一个基于LoRa的数据接收和传输系统。我有两个模块：LoRa E32和LoRa Ra-02。问题是，当我尝试从LoRa E32传输数据时，数据不会传输到LoRa Ra-02模块。这两个模块都配置在433MHz的单一频率上。我不明白如何配置这些模块，它们之间的工作是否可能。
我尝试过更改Ra-02的同步字、频率带宽和扩展系数的设置。在E32上，我更改了空中传输速度，ADDI ADDI。
英文:
I want to create a data reception and transmission system based on LoRa. I have 2 modules: LoRa E32 and LoRa Ra-02. The problem is that when you try to transfer data from LoRa E32, the data does not come to the LoRa Ra-02 module. The modules are configured to a single frequency of 433MHz. I don't understand how to configure the modules, and is it even possible to organize work between them?
I tried to change the settings of the synchroword, the frequency bandwidth, the expansion coefficient to Ra-02. On the E32, I changed the transmission speed over the air, ADDI ADDI.

我之前在其他关于Ebyte模块的问题中已经说过：它们与普通的LoRa模块不兼容。它们的设置与普通LoRa设置不匹配（例如波特率），并且它们缺少普通LoRa设置（SF/BW/CR）。我一直怀疑它们使用FSK而不是LoRa。
你有两个选择：要么只使用Ebyte模块，要么更好的选择是永远不要使用Ebyte模块，而使用Ra、RFM、TTGO、RAK等模块。
英文:
I've said this in other questions about Ebyte modules: they are not compatible with regular LoRa modules. Their settings do not match regular LoRa settings (eg baud rate) and they lack regular LoRa settings (SF/BW/CR). I have long suspected that they use FSK instead of LoRa.
You have 2 options: either you use only Ebyte modules, or, the preferred one, you never ever ever ever use Ebyte modules, and keep with Ra, RFM, TTGO, RAK etc modules.
