This adds a driver for the SPI based AT86RF215 transceiver.
The chip supports the IEEE Std 802.15.4-2015 and IEEE Std 802.15.4g-2012 standard.
This driver supports two versions of the chip:
- AT86RF215: dual sub-GHz & 2.4 GHz radio & baseband
- AT86RF215M: sub-GHz radio & baseband only
Both radios support the following PHY modes:
- MR-FSK
- MR-OFDM
- MR-O-QPKS
- O-QPSK (legacy)
The driver currently only implements support for legacy O-QPSK.
To use both interfaces, add
GNRC_NETIF_NUMOF := 2
to your Makefile.
The transceiver is able to send frames of up to 2047 bytes according to
IEEE 802.15.4g-2012 when operating in non-legacy mode.
Known issues:
- [ ] dBm setting values are bogus
- [ ] Channel spacing for sub-GHz MR-O-QPSK might be wrong
- [ ] TX/RX stress test will lock up the driver on openmote-b
