Does this CC3100 have any limitations in sniffer mode like ESP8266 has ?

i.e packet len i.e no data bytes in frames

Hello,

From CC3100/CC3200SimpleLink™ Wi-Fi®Internet-on-a-Chip User's Guide:

16.11TransceiverModeLimitations
•  The user can open one transceiver socketin the system.
•  The length of a received packet will be trimmed if it exceeds 1472 bytes.
•  Cannot transmit frame over 1472 bytes and below 14 bytes.
•  If using the SimpleLinkstudio, note that the maximum throughputof the SPI is 5~6Mbps,so in  a crowded WIFI medium, there will be packet loss.
•  The transceiver will not open in connection or connected mode. Notice that auto-connection mode is also considered as connected mode, even if not connected.
