Re: AT+CIPSENDBUF with \0 support

2015-10-29T00:20:55+08:00

Bumping again.

Does this seem like a good feature to have in the SDK?

It would be great to have the AT+CIPSENDBUF with the ability to specify the end of the stream without our firmware needing to buffer and count the text in advance.

If it's not feasible, suggestions for us adding as a custom command?

Thank you again for your support!

Hi,

thank you for the reply.

I do understand it currently can not support \0 . My question is: can Espressif make it support \0 in an upcoming library release?

Or, can you share sample code so I can implement a custom AT command that would achieve my goal?

Thank you again.

Hi,

Sorry that AT+CIPSENDBUF can not support \0 .

Could the UART-WiFi passthrough mode help ?

AT+CIPSENDBUF with \0 support

2015-08-26T23:52:06+08:00

for small microcontrollers or when performance and efficiency is critical it would be nice to send variable length data, so messages do not need to be buffered and counted for length before data is sent.

It appears we have this support using the \0 termination with AT+CIPSENDEX. It would be really helpful if AT+CIPSENDBUF also supported this feature.

Would it be possible to improve AT+CIPSENDBUF to also include \0 ?

If not possible in the short term, would it be possible to share sample code in order to implement a custom AT command that implemented AT+CIPSENDBUF with \0 ?

Thank you very much!
