I am implementing mqtt over gsm 800 module interfaced with stm32f103c8


#1

while establishing tcp connection at+cstt return error and at same time on tmft terminal same at command return ok.why this is so?


#2

Give enough delay between each command when running on MCU. On terminals normally enough time is present between each command since they are entered manually. MCU are faster


#3

Thanks now it is working you are right reason was insufficient amount of delay.
