Since I've made tweaks to the BG96 module, I copied the changes to my module and tried it.
The first time failed:

{\"rssi\":{"
[BG96] AT+QISEND response undefined  <<<<< here it stopped
>state()
=undefined
] "\r\nSEND OK\r\n"
>state()
=undefined
] "\r\n+QISTATE: 0,\"TCP\",\"11"
] ".123.33.456\",80,6804,2,1,0,1,\"uart1\"\r\n\r\nOK\r\n"
>state()
=undefined
] "\r\n+QISTATE: 0,\"TCP\",\"1”
] "1.123.33.456\",80,6804,2,1,0,1,\"uart1\"\r\n\r\nOK\r\n"
] "\r\n+QIURC: \"recv\",0,195\r\nHTTP/1.0 504 Gateway Time-out\r\nCache-Control: no-cache\r\nConnection: close\r\nContent-Type: text"
[BG96] [
  "+QIURC: \"recv\"",
  "0",
  "195"
 ]
] "\r\n\r\n+QIURC: \"closed\",0\r\n"
["AT+QICLOSE=0\r\n"
--><html><body><h1>504 Gateway Time-out</h1>
The server didn't respond in time.
</body></html>
] "\r\nO"
] "K\r\n"
>gprs.debug()
={
  socks: [ undefined ],
  sockData: [
    "",
    "",
    "",
    "",
    "",
    ""
   ],
  busy: false }

The second time looked like it worked as the webserver responded, so it was happy with the amount of data it got.

{\"rssi\":{"
] "\r\nSEND OK\r\n"
[BG96] AT+QISEND response "> "
[BG96] AT+QISEND response "SEND OK"
] "\r\n> "
["\"value\":\"99\",\"unit\":\"dBm\"},\"BER\":{\"value\":\"99\",\"unit\":\"%\"}}}]}"
] "\r\nSEND"
[BG96] AT+QISEND response "> "
] " OK\r\n"
[BG96] AT+QISEND response "SEND OK"
]

My guess it might be a timing sensitivity with the prompt??
