EMSGSIZE error

[SameerChouksey]

Hello,

I am trying to send 240 bytes of data when the SF is 7 and the bandwidth is 125KHz. I am able to send the data but frequently getting OSError: EMSGSIZE.

What are the possible reasons for this error and what are the best ways to handle it?

Regards
Sameer

@sameerchouksey do you know if the network is sending MAC commands to the device? If so there could be acknowledgements to send back, which would reduce the max available packet size.

Not sure if those ACKs have priority over the payload though.
