Hi @JiaNa
Yes, you are correct. According to the OL2385 datasheet, the maximum data rate for the 868 MHz frequency band is indeed up to 400 kbit/s. This is the maximum speed at which data can be transferred using this product under ideal conditions. However, please note that actual data rates can vary depending on a variety of factors, including the quality of the transmission medium, the distance between the transmitter and receiver, and the presence of any interference.
