Omega2+ LTE capabilities
I have been looking at the omega LTE but don't see any mention of making/receiving voice calls or SMS messages. Is it possible?
Bump. I would really lite to purchase the LTE board, but need to know it supports voice and SMS. I know the modem supports it via AT commands. Is the full command set supported by the Omega? Is voice and SMS working?
Wondered this myself… I'm looking to replace my current mobile phone and looking at what's on the market, DIY using the LTE version of the Onion Omega sounds like a reasonable option.
The Onion Omega LTE looks to be built around a Quectel EC25 cellular module, and looking at the schematic https://raw.githubusercontent.com/OnionIoT/Omega2-LTE/master/Hardware/R1.1/Omega2-LTE-v1.1-Schematic.pdf (page 5) I see the I²S pins are disconnected.
That said… whilst looking at a rival module, the SIM7600X, I saw mention of an "audio" port…once you feed the appropriate commands via the AT port, apparently 16-bit mono 8kHz PCM streams out the audio USB-serial port.
Knowing this, I had another look at the Quectel datasheets, found this:
Question is, is anyone able to try this with an Onion Omega LTE to confirm whether it works or not?
