uart.write freez esp after execution
Posted: Sun Feb 12, 2017 11:04 amHi everyone,
I just write a piece of code to command a relay throught an esp-01.
I used this http://www.esp8266.com/viewtopic.php?f=160&t=13164&start=8 to find how to command my relay.
My code with MQTT communication :
My problem is the uart.write() works fine (relay change state) but then the esp is freez. I can't get any response.
I'm probably doing something wrong with the uart lib here... ?

Code: Select all
m:on("message", function(m, topic, data)
if data then
print(data)
if data == "ON" then
uart.setup(0, 9600, 8, 0, 1)
uart.write(0, 0xA0, 0x01, 0x01, 0xA2)
elseif data == "OFF" then
uart.setup(0, 9600, 8, 0, 1)
uart.write(0, 0xA0, 0x01, 0x00, 0xA1)
end
end)My problem is the uart.write() works fine (relay change state) but then the esp is freez. I can't get any response.
