Peer to Peer
mDots using 1.0.8 AT Firmware or Library can be configured for Peer to Peer communication. To allow
communication between mDots, configure two or more mDots with the same network settings. Enabling ACKs
guarantees packet delivery; however, this may disrupt higher level protocols such as zmodem or ymodem file
transfers. Communication between mDots is half-duplex, so both ends should not transmit at the same time or
communication will be disrupted.
The frequency can be set for US 915 models. We advise using 915.5-919.7 to avoid interference with LoRa
Networks.
For Europe 868 models, use a fixed frequency, 869.85, with 7 dBm power setting to allow 100% duty-cycle usage.
Configuration
This example sets up each side with identical settings and starts serial data mode. Then, text can be entered into a
terminal on either side and it will show as received on the other mDot.
