UART Communication with LoRa nodule RYLR998

[andyduarte0192]

Hello!!!
Has anyone use the Reyax LoRa module RYLR998 using ESP-IDF?
I'm having problems dealing with AT+SEND command.
I configured UART Port, and sent the config AT commands (ADDRESS, NETWORKID, BAND) to the module. But when I send, for example, AT+SEND=100,5,HELLO, I get +READY as answer (in few lines I programmed to print in serial monitor what was the answer after a certain command). Shouldn't it be +OK? Or does it means the module got a reset somehow?
