- Mon Dec 22, 2014 10:34 am #5435 I found espconn_sent of this release has different behavior than 0.9.3.

In 0.9.3, I can call this function continuously and having all the strings delivered. But in this release if I call this function several times, all network sending seems stalled.

To verify, compile of "ESP8266 UART to TCP socket absolutely transparent bridge " in this topic viewtopic.php?f=6&t=864 sending data from UART to TCP will stall after some time.

I guess it is buffering problem but yet to verify.

extern SpiFlashChip * flashchip;

----------------- Sample:
if(flashchip != NULL) os_printf("FlashID: 0x%08x\nChip size: %d\nBlock size: %d\nSector size: %d\nPage size: %d\nStatus mask: 0x%08x\n",
flashchip->deviceId, flashchip->chip_size, flashchip->block_size, flashchip->sector_size, flashchip->page_size, flashchip->status_mask );
else os_printf("Unknown Flash type!\n");

It's not a bug, it's a feature: http://bbs.espressif.com/viewtopic.php?f=13&t=92
