Hell guys, hope you are well… i have some questions about EC200AAUHA-N06-SNASA:
Does this specific model is supported in QuecPython?
I saw this module support RMII Ethernet, that ethernet is usable with quecpython to access internet? If yes then which Ethernet PHY chip is the recommeded for this specific model…
Can be used 4G internet and ethernet internet at same time to example send data to mqtt or at least use 4G as primary internet and ethernet as fallback or viceversa?
Does this specific model support audio playback with quecpython? need an external codec or only need audio amplifier?
Does this specific model support C-BUS used by CML Microcircuits devices in quecpython?, this is basically like a modified SPI: C-BUS is a proprietary half-duplex variant of SPI developed by CML Microcircuits. Both protocols are synchronous, but while standard SPI is inherently full-duplex (transmitting and receiving data at the same time), C-BUS requires a specific sequence to read and write data.
When using quecpython an UART port, example UART1 to let the user configure parameters of the device through uart1, that uart1 port is visible when connected using the native usb as a virtual com or need an serial to usb for that specific uart1?
3, Yes, the EC200U supports using 4G and Ethernet simultaneously.
4, Yes, the EC200A supports audio. You do not need to add an external codec; however, if you need higher output power, you may need to add an audio amplifier.
5, The EC200A does not support C-BUS natively. However, based on my online research, it may be possible to implement it using SPI.
6, Yes, the EC200A supports UART. If you connect the UART to USB, a USB-to-serial converter will be required.
If you have any further questions, please don’t hesitate to let us know.
Thank you for taking the time to reply, I really appreciate it.
I see you said EC200U supports using 4G and Ethernet simultaneously, but im talking about EC200A, does EC200A support? and i checked the API (umqtt - MQTT Protocol - QuecPython and usocket - Socket Module - QuecPython) and i dont see that umqtt and socket.connect(address) support to use an specific network interface so can be choose 4g interface or ethernet interface, does umqtt and socket.connect(address) choose automatically which use (either 4g or ethernet)? How can i choose an specific network interface (example ethernet) so it send data through that specific network interface while have 4G enabled to use as fallback?
I see you said EC200A support audio, it support mp3 audio playback? (I have that doubt because in audio - Audio Playback - QuecPython show that only EC200U Series support audio playback). and what its the audio output quality when playing an mp3? 16bits - 44khz?
What its the available Flash storage and RAM for python scripts for this model EC200AAUHA-N06-SNASA?
Oh, I am sorry. I made a mistake. I meant EC200A, not EC200U.May I ask whether your usage scenario requires the module to connect to the network via both 4G and Ethernet simultaneously? If so, yes, the module does support it. However, there is only one path for data transmission. We usually use set_default_NIC to decide whether to use 4G or Ethernet. For details, please refer to the attached file.
The EC200A supports audio, but the official firmware does not support this function by default. If this is a strong requirement, I can check with the internal team to see which version supports audio. And the MP3 only supports 16bits-22.5khz.
The available space of flash is 704KB, and the available of memory is 512KB
Regarding sound support in EC200A, yes, please, it would be useful for playing local notifications with MP3 audio files and for notifying user of activity and internet outages/change so it will stay informed. Does that 16bits-22.5khz its the output quality of internal hardware codec of EC200A?
