"TxParamSetupReq" MAC Command


I have a AS923 device which able to uplink alarm messages to TTN with 17 byte before, but recently TTN cannot receive anymore uplink alarm message…

Then I noticed the current “TxParamSetupReq” MAC Command limited the payload to 11 byte, which affecting the uplink messages from my device to server…

May I know can we avoid the 11 byte payload size limit?
