I am testing with the BG96 and currently performing http post with server response. It seems if the response from the server is greater than around 1500 bytes then at the BG96 I receive nothing:
22/01/20 17:00:09.963 INFO: RX> "+QHTTPPOST: 0,200"
Any response from the server less than 1500 bytes is fine:
22/01/20 17:28:34.441 INFO: RX> "+QHTTPPOST: 0,200,1424"
Of course this limitation is not normally present in http. See for example here:
Is this a limitation imposed by the BG96 when using http?
