I’m developing a project with the module SIM868 using Bluetooth. I’m facing some problems and I hope you can help me.
Right now, I’m able to connect to a device with 4 digit password using the following commands:
• AT+BTPAIRCFG and AT+BTPAIR
Then I’ve tried to connect to a device (the same Bluetooth module and everything the same) but with 8 digit password. The point is that the command AT+BTPAIRCFG doesn’t accept 8 digit password. The device can pair correctly but then when is going to connect, it can’t.
Is there any way to connect to a 8 digit password like I’m doing with the 4 digit password?
Is there any way to connect to a device with an 8 digit password? Sometimes I’m able to pair with it but not to connect.
Thanks in advanced!!
