Hi All!
I am using Zephyr RTOS NCS v2.0.2.I used uart_central and uart_peripheral apps. But it Can only connect one peripheral with central at a time. Is it possible to connect the multiple peripheral connections with central like 20+ as promised by the zephyr?
My main goal is to send the sensor data from each node/peripheral to the central. Can you please guide me in this regard?
Thanks
Regards,
Hi Amanda Hsieh
I tried to compile the Multi Nus project in Vs code studio. I am using NCS V2.0.2. I got the following errors can you help me in this regard?
