An ESP8266 SDK Firmware with AT command to submit data to Google Form.
- Directly submitting data to Google Form.
- SSL implemented for submitting data (As Google forced it)
AT+GFORMSUBMIT=<Google_form_ID>,<Total_entries_n>,<Entry_1_data>,<Entry_2_data>,<Entry_n_data>,...
Where:
<Google_form_ID> = Your Google Form ID
<Total_entries_n> = Total entries that will be submitted to Google Form, usually this equals to how many text box/input in your form
<Entry_n_data> = Data to be submitted, must in the form of name and value pair, i.e.: entry.1335153026=data_for_this_entry
-
Given the form link is:
https://docs.google.com/forms/d/1bg-8CAyVF3Rq3Q_1Z87BLxUrE4aKB1AEMhkXyQAl-u4/viewform
-
<Google_form_ID>=1bg-8CAyVF3Rq3Q_1Z87BLxUrE4aKB1AEMhkXyQAl-u4 -
<Total_entries_n>=2 -
Entry IDs=entry.1335153026,entry.1490820559(Try to view source code of the form, or follow this to get the pre-filled link to extract the entry IDs)
Execute the following command to submit the Google Form
AT+GFORMSUBMIT=1bg-8CAyVF3Rq3Q_1Z87BLxUrE4aKB1AEMhkXyQAl-u4,2,entry.1335153026=answer_for_question_one,entry.1490820559=answer_for_question_two
- Try not to put big (lengthy) data, the ESP8266 does not have much RAM after we used the SSL library
- Request packet buffer size is
224, could be changed inat_gformCmd.c, but it is recommended not to modify the value. - SSL buffer size is
4608, could be changed inat_gformCmd.c, but it is recommended not to modify the value. - Comma (,) is not allowed in any fields including
<Google_form_ID>,<Entry_n_data> - Remember to put \r\n after each command (complies with the original AT FW specifications)
- Application may reset when sending command too fast
- Need to add packet echo to avoid data drop (very weird)
