- targets python version 3.9
- Allow setting a specific modem when initializing a network. This can be done by passing the modem into the
HologramCloudintializing method for example:HologramCloud({}, authentication_type='totp', network='cellular', modem=modem). Initialize a modem using one of the following methods:- Initialize a modem object with a known good port using a supported modem class in
Hologram.Network.Modemfor example:EC21(device_name="/dev/ttyUSB4")This initializes a Quectel EC21 on port/dev/ttyUSB4 - Scan for all available modems through the new
Cellular.scan_for_all_usable_modems()method atHologram.Network.Cellular. This returns a list of accessible intialized modem objects. Just pass one of these in as a modem.
- Initialize a modem object with a known good port using a supported modem class in
- Allow modems to send SMS messages through the modem interface. For example:
hologram.network.modem.send_sms_message("+80112", "Hi dashboard!"). Note: Extra charges for sending SMS with this method may apply
