Hello Receive examples

[matoxbr]

Guys in the examples folder just found it for shipping. Does anyone have an example to receive? thanks

Hi,

receiving is not officially supported yet. I implemented some basic support (private / unstable API).

You can receive packages by calling transceiver._wait_for_packet(timeout_seconds=21, gdo0_gpio_line_name="GPIO25") (or similar)

Example: https://github.com/fphammerle/wireless-sensor/blob/v0.4.0/wireless_sensor/init.py#L150

Currently, I cannot guarantee backward-compatibility in future releases yet (thus, the method has a _ prefix)

Hello,

Do you plan to add receiving support? :)

Thanks

[fphammerle]

Yes, I do. Actually, I have been using transceiver._wait_for_packet for several months already but I haven't found time to make the method / API public yet.

Yes, I do. Actually, I have been using transceiver._wait_for_packet for several months already but I haven't found time to make the method / API public yet.

I assume you are using the FIFO buffer due to pythons slow speed?

[fphammerle]

Yes, see CC1101._get_received_packet. In summary:

self._read_burst(
    start_register=FIFORegisterAddress.RX,
    length=self._read_status_register(StatusRegisterAddress.RXBYTES)
)

Hello! I have a WS90 weather station, a Respi zero2w, a cc1101. I tried to receive the signal the way you did but failed. So I just need a simple example to receive fsk2 signal. Thanks!

[fphammerle]

Hi, sorry, I do not have enough resources/time to provide support. You first need to know all the properties of the FSK2 signal (center frequency, bandwidth, sample rate, preamble/sync word) and configure CC1101 accordingly. I would recommend analyzing the signal with a RTL-SDR receiver first.
