Simon,
If I was not clear, my apologies... lots of RAM due to the use of SSL and not LwIP BR, Noam. ________________________________ From: lwip-users <lwip-users-bounces+noam=silrd....@nongnu.org> on behalf of goldsi...@gmx.de <goldsi...@gmx.de> Sent: Wednesday, May 17, 2017 9:34 PM To: Mailing list for lwIP users Subject: Re: [lwip-users] HTTPS support in lwip Noam Weissman wrote: First of all the code is still in development and secondly you need lots of RAM. That "lots of RAM" is a limitation of TLS, not a limitation of mbed TLS or how lwIP uses it. That code is still not finished though. And I have to come up with RAM/ROM numbers once it is finished... Anyway, for devices where HTTPS is only one out of many services, that usage is far from ideal as it encrypts/decrypts data in the tcpip_thread. And during potentially slow/long encrypt/decrypt phases, nothing else can be done in lwIP (e.g. no packet processing, no ping, no ACKs...). A socket or netconn-based server might be a better idea for some... Simon
