No. 660	TCP/IP connection issue with CIEM10 module	2012-03-19

Hello, I just bought a CIEM10 module and it is working very well when controlled via a PC with Internet explorer but I have the following issue when trying to control the module via a smartphone / HTML browser. CIEM10 log shows the error "http_notify_rcvd: data too big 800" and the Smartphone gets no reply from CIEM10. The configuration is the following. All devices are connected to a 192.168.1.xxx local network with a WIFI TCP/IP hub: - CIEM10 is connected to the WIFI TCP/IP hub via an ethernet cable. CIEM10 IP address is 192.168.1.5 - Smartphone is connected, via WIFI, to the WIFI TCP/IP hub. Smartphone IP address is 192.168.1.101 - PC (running Windows XP) is also connected, via WIFI, to WIFI TCP/IP hub. PC IP address is 192.168.1.102 The CIEM10 log for the connection which fails with Smartphone is : [19:41:03 424576] [00:30:F9:0B:02:2B] [71] ip: rcvd: 192.168.1.101.1323 > 192.168.1.5.80: SYN seq: 2814536056 len: 0 win: 65535 [19:41:03 425735] [00:30:F9:0B:02:2B] [72] ip: sent: 192.168.1.5.80 > 192.168.1.101.1323: ACK SYN seq: 81159 ack: 2814536057 len: 0 win: 800 [19:41:03 432860] [00:30:F9:0B:02:2B] [73] ip: rcvd: 192.168.1.101.1323 > 192.168.1.5.80: ACK seq: 2814536057 ack: 81160 len: 0 win: 65535 [19:41:03 434928] [00:30:F9:0B:02:2B] [74] ip: rcvd: 192.168.1.101.1323 > 192.168.1.5.80: ACK seq: 2814536057 ack: 81160 len: 800 win: 65535 [19:41:03 435497] [00:30:F9:0B:02:2B] [75] http_notify_rcvd: data too big 800 [19:41:03 436706] [00:30:F9:0B:02:2B] [76] ip: sent: 192.168.1.5.80 > 192.168.1.101.1323: ACK FIN seq: 81160 ack: 2814536857 len: 0 win: 800 The CIEM10 log for the similar, but working, connection with PC/windows XP is: [19:49:05 675083] [00:30:F9:0B:02:2B] [58] ip: rcvd: 192.168.1.102.49163 > 192.168.1.5.80: SYN seq: 3470834782 len: 0 win: 8192 [19:49:05 676325] [00:30:F9:0B:02:2B] [59] ip: sent: 192.168.1.5.80 > 192.168.1.102.49163: ACK SYN seq: 43392 ack: 3470834783 len: 0 win: 800 [19:49:05 678813] [00:30:F9:0B:02:2B] [60] ip: rcvd: 192.168.1.102.49163 > 192.168.1.5.80: ACK seq: 3470834783 ack: 43393 len: 0 win: 17520 [19:49:05 684555] [00:30:F9:0B:02:2B] [61] ip: rcvd: 192.168.1.102.49163 > 192.168.1.5.80: ACK PSH seq: 3470834783 ack: 43393 len: 561 win: 17520 [19:49:05 685767] [00:30:F9:0B:02:2B] [62] ip: sent: 192.168.1.5.80 > 192.168.1.102.49163: ACK seq: 43393 ack: 3470835344 len: 0 win: 800 .... Please, could you tell me if there is any way to solve the above issue (eg change maximum received length on CIEM10 module)? Many thanks.
