Currently, I am able to use Mqtt Publisher or Subscriber with only one Nrf52 device. I can ping to the device with link-local address.
I am using Nrf52832 with SoftDevice 132 in keil. I am currently using Sdk 15.2.0.
However, when I connect other Nrf52 device to make same Mqtt example with one Rpi3 as broker and 2 Nrf52s. The connection get freezed and I could not send ping and buttons do not work as well.
I have read the thread with the topic same with mine:
devzone.nordicsemi.com/.../multi-connection-of-ble-6lowpan-border-router
but I could not understand how to implement that patch. Since I am so new to linux. In my previous question I was so amateur to ask question, forgive me for that.
