How do I know if the ebyte e32 ttl100 module is broken? #23

hello Renzo, First of all thank you very much for writing the library, I used it many times.

but now I have a problem: i connected the arduino mega and the e32 board without a pull-up resistor in between Especially m1 m0 rx tx pins and after that I could not communicate, As far as I know the card should work like this, I remember it was a recommended use in the datasheet. How can I tell if the card is burned now? using a network analyzer, for example Or is there a library that checks that the uart connection is working properly?

or i hope you know better

Hi, When I have a problem with e32 first I try to do a reset from the library, than I try with the official Ebyte software, than I use a logic analizer and check if data are transmitted to the serial and AUX pin change status.

Logic analizer is inexpensive but very important to debug serial i2c or spi.
