Infinite packet length mode #141

Open LennP opened 1 year ago

LennP commented 1 year ago

Hi,

I am trying to use this library to send packets that are about 600 bytes long using a CC1101. I see the PacketLengthMode.INFINITE has been commented out in the options.py file. Is this because it has not yet been implemented?

Best regards, Lenn

Hi,

yes, currently the library does not yet support PacketLengthMode.INFINITE (missing implementation).

Use of PacketLengthMode.INFINITE is documented in section 15.2.2 "Packet Length > 255" of CC1101's manual: https://www.ti.com/lit/ds/symlink/cc1101.pdf

With the current implementation you could use CC1101.asynchronous_transmission() instead. However, that mode requires manual encoding and timing of the signal (by setting pin GDO0)

Hi,

Thanks for your reply. So if I'm right you have not given it a try to implement it, therefore it would likely be possible?

Yes, I haven't tried yet but I assume that it is possible with a few hours of effort
