Good afternoon, I put together a circuit and recorded the signal from the drone control panel on HackRF with a frequency of 2.4 GHz, saw on the spectrum that LORA was transmitted and wanted to demodulate, opened the recommendations and the characteristics of the signal and drove into the circuit

But when demodulating, the error Header Checksum invalid

Can you help. I just tried to set various other parameters and according to other recommendations that are only available on the Internet, but alas they did not display anything. I tried to enter, let's say this is SX128x - LoRa
Begin method:
Carrier frequency: 2400.0 MHz
Bandwidth: 812.5 kHz (dual-sideband)
Spreading factor: 9
Coding rate: 4/7, long interleaving disabled
Output power: 10 dBm
Preamble length: 12 symbols
Other:
LoRa header mode: explicit
LoRa CRC: enabled, 2 bytes
Inaccessible:
LDO regulator mode: disabled (SX128x module with DC-DC power supply)
Number of CAD symbols: 8
But unsuccessfully, and now more or less something has appeared.

Why is this in Russian? I guess if you can't be bothered to translate and post in English, anyone who can help you will probably also not bother...
