While downloading responce from server:
+QIRDI: 0,1,0,1,773,773
0, CLOSED
AT+QIRD=0,1,0,512
ERROR
It is unnable to get those 773 bytes.
How to solve this?
hi，
Under normal circumstances, if the server is disconnected, the data cannot be read. Can you send the at instruction of the normal process? thanks.
It is strange answer…
Data is in module’s buffer. Server connection closed, true. But why can’t I read those “already received” bytes?

hi,
If the data is already in the cache, it can normally be read.
Please read with AT+QIRD=0,1,0,1500 to see if there is an error.
thanks.
