Hello, is there a way to know the total size in bytes of the message (struct) sent?
In case:
header size (RSSI + …) + body/payload size (sturct) + library encryption size (KeeLoq) + Ebyte encryption (CRYPT_H + CRYPT_L)?
This is very important information to know if the LoRa transmission complies with local legislation.
In some countries, the transmission cannot be longer than 400 milliseconds, and knowing the message size (head+body+encryption) is required.
Hi Renzo
About that post, the total byte size of the message would be something like:
+ 3 bytes - CHAN, ADH, ADL of Recipient
+ X bytes - Payload Message (Ex: size_of(strutc))
+ 1 bytes - RSSI (If enabled)
Does cryptography (CRYPT_H + CRYPT_L + KeeLoq method used in the library) not influence the final size of the message?
Thanks
Hi George,
sorry if I didn’t answer this topic, but to understand the problem better, I contacted EByte directly; I didn’t receive any satisfying information.
I think you can try to contact It to add pressure to the request.
Bye Renzo
