Hello, who can tell me what hardware runs with all functions?
Where do you get these modules.

Hi

What specific functions are you after? as most modules I've seen are pretty similar in features.

I've had good results using these modules

However I was only interested in creating a transparent link between them, which worked with ease.

Many thanks chipfryer27

can the module from AZ communicate in both directions?
I ordered some and I had one similar to this. it looks so similar ber works only in one direction.
it sends to the smartphone via bluetooth but not back from the smartphone. the two chips on the module have the same names. can it be that they react differently?
the AT commands for example also do not work as specified.

Hi

I can confirm bidirectional communications using these modules and I've not had any issue with AT's. My last play with them is here

Do note that depending on vendor, the baud when configuring may be different to the usual 38400.
