Question relating to:

Last updated: 09 Nov 2021
The MultiConnect® mDot™ offers significantly longer range and improved radio performance compared to traditional wireless solutions—resulting in greater transmission range and reduced capital expense.

Update to this. With the 1.0.8 firmware mDot to mDot communication is now a feature. It allows a channel to be setup between mDot configured with the same LoRaWAN settings. Configure each dot with Network Address and Session Keys. Each mDot configured with these settings will be able to receive and decrypt the packets. There is not a protocol built-in to handle full-duplex communication so only one mDot should transmit at a time.

An application protocol must be put in place to coordinate transmit in a N to 1.

There is no support for peer to peer communication in the libraries provided by Multitech. We are currently working on supporting that as a feature in the library.

However it is possible to write a custom application that uses the SX1272 radio to transmit on the same frequency/datarate that another is listening on.

Here are a couple programs that use just the SX1272 on mDot: https://developer.mbed.org/users/dudmuck/code/sx127x_simple_TX_mDot/ https://developer.mbed.org/users/dudmuck/code/sx127x_simple_RX_mDot/

Thanks for this link Jason. Can we do N to 1 peer to peer, or is it only 1 to 1?
