I am sending “AT\r\n” to the esp RX pin (tested on D9 and signal is good) but am not receiving the OK message back.
Upon startup I receive a message over UART from the ESP saying:
ets Jun 8 2016 00:22:57 rst0x1 (POWERON_RESET),boot:0x13 (PI_FAST_FLASH_BOOT) configsip:0, SPIWP:0xee clk_drv:0x00,q_dv:0x00,d_drv:0x00,cs0_drv:0x00,d_drv:0x00,wp_drv:0x00 mode:DI, clock div:2 load:0x3fff0018,en:4 load:0x3fff001c,len:756 oad:0x40078000,len:4892 load:040080000,len:6476
The AT signal that is sent seems to be correct and I am receiving signals back from the ESP, so what could it be? I’m beginning to wonder if the AT Command firmware isn’t installed on the ESP?
