Hi All,
Need help over here.
Please help.
I am testing on CR1000 OS 32.03 sending the data via the FTPClient and the EmailRelay. Data interval every minute and send them every 2 minutes. My program as below.
For the FTP is working fine. but for the EmailRelay, Email was received with an empty .dat file attachment 0KB.

The FTPClient works because the file it is looking to send is defined in variable "LastFile" which is generated by the "TableFile" instruction in the output table.
Your "EmailRelay" instruction asks to attach "Email_Attachment" which is set to look for "USR:NCC_logger1_ftp.dat", which does not exist. No instructions create this file. It maybe simpler to attach the data directly from the Tbale itself, using the optional parameters.
Please note, EmailRelay has a daily maximum on the number of emails that can sent through this free-of-charge service. I believe this is 100 per day.
Hi nsw,
Thanks for your reply.
Much appreciate if you could share a short program of sending data using “EmailRelay” instruction.
Thanks in advance.
Even though this is the help for the CR1000X, the same parameters and examples can be used on the CR1000. https://help.campbellsci.com/crbasic/cr1000x/#instructions/emailrelay.htm%3FTocPath%3DCR1000X%2520Instructions%7CInternet%2520Protocols%7C_____3
Hi Gary,
Thanks for your help.
EmailRelay is working now. i am able to received the email with data.
I have 2 more questions.
1. I am getting EamilRelay's ServerResp -2, under what situation will the streaming interval become true?
2. Can I program to send out the 24 hours data daily at 8am specifically?
Hi all
i am having same problem with CR310 datalogger.
Sending the data via the EmailRelay.
The Email was received with an empty file attachment.
thank you.
Check you have the latest OS loaded in the CR310. Latest OS revision is 10.06. An earlier version had a bug with EmailRelay and zero file sizes in attachments.
