Receive more than 64 bytes

[kraef]

Is it possible with the mkr wan to send and receive a message with size more than 64 bytes??

I have been using the RAK811 shield for Arduino for 2 months. On that shield, I was not able to send a payload of larger than 64 bytes even at a DR larger than 3.

This table shows the size limit of payload when the module is set to different DR. (Source: LoRaWAN™ 1.0.2 Regional Parameters.)

I am curious if the MKR WAN 1310 has the same limitation as well before I get one. Thank you.

Unfortunately it's hardcoded in the middleware and chip driver for the 1.2.x firmware. Maybe that changes for the newer releases

I performed a update to the firmware which now supports 242 bytes HEX or 121 bytes binary send, and 242 bytes receive (= 250 incl Mac header). Local tests seem ok. Should be merged soon to fw ver 1.2.4.
