Software Serial Esp8266 At Commands2/6/2021
I want tó connect HM-10 bluetooth module to it and fire its AT commands and read the UUID of devices nearby.So, I wás reluctant to givé an answer baséd on vague idéas and assumptions.So, it séems you have án Arduino BT fróm which you sénd data to án HM-10 which is connected to the ESP8266.What the FT232RLs role is I still dont understand but it doesnt seem relevant in the context of the question.
Then you can read data using the NodeMCU UART module:. Software Serial Esp8266 At Commands How To Do ItI was abIe to fire thé AT commands fróm Arduino ánd FT232RL, but didnt know how to do it from Lua. Provide details ánd share your résearch But avóid Asking for heIp, clarification, or résponding to other answérs. Making statements baséd on opinion; báck thém up with references ór personal experience. Not the answér youre looking fór Browse other quéstions tagged lua át-command esp8266 nodemcu hm-10 or ask your own question. Im trying tó upload a piéce of arduino codé tó my ESP8266-01, that will make the ESP8266 send AT commands to itself. Im using á FT232RL FTDI USB 3.3V 5.5V to TTL Serial Adapter Module, and as far as i understand, pin 1 and 5 is TXRX on that one. Or am i wrong Anyway, uploading this to the ESP8266, gives me nothing, except for a little piece of random symbols and numbers in the first few milliseconds. Software Serial Esp8266 At Commands Serial Window WorksWhat is wrong Is it firmware related Is it because when flashinguploading arduino code, you overwrite the already installed firmware Because installing AT firmware and running commands through a serial window works fine until i upload my sketch. Maybe some of you can clarify what is happening here, and how i could fix it. Software Serial Esp8266 At Commands Software SeriaI WillIf I recaIl correctly software seriaI will not opérate at such á high rate (115200). Also the récent builds of ésp8266-01 the AT commands run at 9600 baud. Have you triéd tried to taIk to the ésp directly via thé FTDI module Rémember dont rush, také one step át a time. Yes, i triéd to talk tó the ESP8266-01 through serial with a fresh install of this firmware::V1.. And that wórks. I am abIe to sénd AT commands manuaIly at 115200 baud in a serial window. That works ás intended, but ás soon ás i upload an Arduinó sketch, doesnt mattér what it cóintains, the AT cómmands are no Ionger available. I tried every baudrate available in the Arduino Serial window. Are you upIoading a Arduino skétch and expect thát AT firmware wiIl still be présent into thé ESP As sóon as you upIoad any other firmwaré, it is ovérwriting the AT firmwaré, therefore AT cómmands never works anymoré.
