Recipient address #6

Open sea-of-rob opened 2 years ago

sea-of-rob commented 2 years ago

In the original docs for raspi-lora library they state that a message can be broadcast to all devices irrespective of their address:

header_to Address of recipient (0-255). If address is 255, the message will be broadcast to all devices

Is this supported as I cant get it to work with:

lora.send("This is a test message", 255)

Thanks

I'm also having the same issue. How to broadcast a message using this library?

barryhunter commented 1 year ago

There is a bug in this library, kinda inheritied from raspi-lora. Even raspi-lora wouldnt receive broadcast messages, unless receive_all was used. This project tried to fix it, but not quite.

I found and fixed this in my own fork of this project https://github.com/barryhunter/u-lora/commit/685edbc60dfe9d3bff405ef586f71253269da6b8#diff-82727dcdad31bd5c8d91b972f851b604138ffea43ff5512d7a5ffe18c98be460L351

Or get it from https://github.com/barryhunter/u-lora/tree/patch-1

Which was found when comparing with https://github.com/epeters13/pyLoraRFM9x/ (so they get the credit for getting it working!)

Can also use receive_all on the receiver with current u-lora library.
