ESP8266 + GSM Neoway M590
Posted: Mon Nov 02, 2015 4:04 pmConnected GSM Neoway M590.
With external power 5V its work perfect on Arduino Uno, but same not work properly in ESP8266.
Neoway M590:
edge 1 - 5V external,
2 - gnd external+gnd esp8266,
7 - gsm TX->gpio 12
8 - gsm RX->gpio 13
At commands ok, register in network ok, sometime send sms )
but not receive sms and after some time module not respond or unregister network.
Tried connect TTL 5V->3.3V on RX/TX, but in this case not work even at commands.
Any ideas? May be somebody already solve all problems by this module?
Softwareserial library in attach.
+70001111111 replace on your phone.
