Other Parts Discussed in Thread: CC1101, SIMPLICITI
I'm using SMARTRF-TRXEB PCB rev 1.5 with CC1101 and Packet Sniffer application to sniff SimpliciTI protocol packets from a network I'm developing using SimpliciTI. The sniffer works when SimpliciTi radio settings are default (2-GFSK, 902MHz, 250kbaud, 540kHz Rx Filter, 200kHz channel spacing, 127kHz deviation, channel 20, Manchester disabled, 30/32 sync, preamble count 4, DC filter disabled). But, if I change radio settings to DC filter enable and change the modulation to 2-FSK (both in the SimpliciTI devices and in the sniffer) my SimpliciTI devices communicate properly, but the sniffer doesn't pick any packets. If I continue using 2-GFSK and enable DC filter, SimpliciTI devices stop communicating as well, and the Sniffer still doesn't see anything. Basically, the Sniffer only managed to sniff packets for me if the DC filter was disabled. Any thoughts on this? Why is it so?
PS. I'm using the following radio settings:
2-FSK, 20kHz deviation, 38.4kBaud, 120kHz Rx bandwidth, 150kHz channel bandwidth, Manchester disabled, 30/32 sync, preamble count 4, DC filter enabled, 4 channels
2-FSK, 50kHz deviation, 100kBaud, 250kHz Rx bandwidth, 300kHz channel bandwidth, Manchester disabled, 30/32 sync, preamble count 4, DC filter enabled, 2 channels
2-GFSK, 127kHz deviation, 250kBaud, 540kHz Rx bandwidth, 400kHz channel bandwidth, Manchester disabled, 30/32 sync, preamble count 4, DC filter disabled(doesn't work with enabled), 1 channel.
