Re: SPIRAM UART init
hallo davef, yes you are right, i have found the same with v.1.14 versions #esp32-idf4-20210202-v1.14.bin self.gps=UART(1, 9600) self.gps.init(tx=self.tx, rx=self.rx) #esp32spiram-idf4-20210202-v1.14.binhall self.gps=UART(self.uart_bus, 9600, tx=self.tx, rx=self.rx) just a note: you need to do the s...

Re: hc-12 uart debug
i look's like it has to do something with wiring. even i try to have all in order i found out - when repl + usb disconnected, another machine start to reproduce the same error - on client with hx711, i have also removed oled and ads1115 - as mentioned here https://www.allaboutcircuits.com/projects/u...

Re: uart respode from Lora611
thank you, got the results now. i did a few mistakes
a: first, i have wrongly understand manual, so for AT commands to work the module SET pin needs to be put LOW
b: as you mention, uart.read() does not wait, so for my test purpose i create infinite loop and grab the results
thank you again, pavel
