LSatan / SmartRC-CC1101-Driver-Lib

This driver library can be used for many libraries that use a simple RF ASK module, with the advantages of the cc1101 module. It offers many direct setting options as in SmartRF Studio and calculates settings such as MHz directly.

Rebooting...

I'm using ESP32_DEVKIT-V4 and CC1101 868MHz module (green one) header configuration is:

ELECHOUSE_cc1101.Init(); // must be set to initialize the cc1101! ELECHOUSE_cc1101.setCCMode(1); // set config for internal transmission mode. ELECHOUSE_cc1101.setModulation(0); // set modulation mode. 0 = 2-FSK, 1 = GFSK, 2 = ASK/OOK, 3 = 4-FSK, 4 = MSK. ELECHOUSE_cc1101.setMHZ(868); // Here you can set your basic frequency. The lib calculates the frequency automatically (default = 433.92).The cc1101 can: 300-348 MHZ, 387-464MHZ and 779-928MHZ. Read More info from datasheet. ELECHOUSE_cc1101.setSyncMode(0); // Combined sync-word qualifier mode. 0 = No preamble/sync. 1 = 16 sync word bits detected. 2 = 16/16 sync word bits detected. 3 = 30/32 sync word bits detected. 4 = No preamble/sync, carrier-sense above threshold. 5 = 15/16 + carrier-sense above threshold. 6 = 16/16 + carrier-sense above threshold. 7 = 30/32 + carrier-sense above threshold. ELECHOUSE_cc1101.setCrc(0); // 1 = CRC calculation in TX and CRC check in RX enabled. 0 = CRC disabled for TX and RX.

any ideas? Thanks

found problem... byte buffer[99] was to small, changed to buffer[999] and now it's working

@LSatan Why is the buffer more than 61 needed ? Hope CC1101 needs only 61 bytes ?
