RAK11720 like BLE client

LPWAN Modules / EVBs RAK11720

Hello,

I have a RAK11720 with a custom service for transmitting ADC converter values. My application is working fine; I can read the values with my smartphone using NRF Connect. I can see the characteristics and notifications on my smartphone.

My question is: Is it possible to program another RAK11720 to act as a BLE client? I’ve read the RAK11720 API documentation, but I haven’t found a way to make the RAK11720 function as a client. I’ve only found how to scan for MAC addresses, but I can’t connect to a device.

There are no API commands or AT commands for this functionality.

When will the new firmware version with these new functions be released? Or is there another way to program the RAK11720 for this purpose?

Hello @and-tecnipak,

Did you mean you want to prepare a central device that connects to your peripheral device? If question is this, it is not possible to create a central BLE device with RUI3, unfortunately.

It is possible to scan for BLE devices, but it is not possible to connect to a device.

Best regards,
Sercan.
