the question of ble central and peripheral

[xiang san]

Hi,

    I have a question, I use a 52840 board as the Bluetooth center. The protocol is S140. The other 51822 board is a Bluetooth peripheral. The protocol is S130. The routine I use is "blue_app_uart". But I find that the Bluetooth of these two boards cannot be connected. Is it because the protocol versions are different?

Thanks!

Hello,

Working on two different Bluetooth protocols on different boards should not be the problem. You can first try with one board as peripheral and try to connect this board from nRF Connect on android or ios. 

We also need more information about your boards; are these DKs or board? If possible you can send the hardware file as well. 

Thanks.

Hi,

     I have solved my question.The center and peripherals can be connected between different Bluetooth protocols！

Thanks very much!

Yes, a Bluetooth protocol is a backward compatible so that should not be a problem. Great to hear that problem is solved.
