I purchased 3 HC-05 bluetooth modules on Amazon here: https://www.amazon.fr/dp/B0722MD4FY
I'm trying to set up a first test by pairing 2 bluetooth modules: Connecting 2 Arduinos by Bluetooth using a HC-05 and a HC-06: Pair, Bind, and Link | Martyn Currey
I managed to execute the following AT commands:
AT+RMAAD : clears any previously paired devices.
AT+ROLE=1 -> Master Mode
AT+CMODE=0 allows to connect to any device
AT+INQM=0,5,9 set inquiry to search for up to 5 devices for 9 seconds
AT+INIT -> I get ERROR(17)
AT+INQ -> I get ERROR:(1F)
Looking at forum posts, it seems to be an issue with my HC-05 version
AT+VERSION -> VERSION:3.0-20170601
It seems that version 2 modules work fine. How can I find a vendor selling HC-05 in the working version?
Unless there's a solution with v3 ..?
