why does not my DIS02170A(CrowPanel Advance 7“ HMI) with the lora add-on module support meshtastic
customer question:
"I ordered the: DIS02170A-DAC00105W with the lora radio add-on
which in the description says it supports Meshtastic. I now see that you have a separate listing on your website for the same screen that comes with the lora radio for meshtastic. Are these different? What is different that does not allow one to support Meshtastic over the other”
our reply:
"We’re very sorry for the misunderstanding, which may have been caused by the similar appearance of the products. In fact, the device you purchased is mainly designed to be used as a regular HMI display. This screen can add a LoRa add-on module, but the module is primarily intended to provide LoRa functionality.
The version of the screen that can run Meshtastic is based on our V1.0 hardware of the 7-inch display, developed in collaboration with the official Meshtastic team. They created dedicated Meshtastic firmware for that hardware and allowed us to register the device through the official Meshtastic channels. However, due to a technical limitation—LoRa and TF card functions cannot coexist—we never officially released the Meshtastic 7-inch version for sale.
Currently, only three displays are fully and officially supported by Meshtastic: 2.4-inch, 2.8-inch, and 3.5-inch. (Here is the link for the 3.5-inch version:)

The 7-inch devices you may have seen mentioned on Discord or other channels are DIY projects by enthusiasts, who purchased our V1.0 hardware and added LoRa modules themselves.
Unfortunately, the hardware version of the product you purchased is V1.2, which not only does not support the previous official Meshtastic firmware, but also will not be supported by Meshtastic with any firmware in the future.
Looking ahead, we are planning to launch a new 7-inch display with the ESP32-P4 as the main controller in early September. For this version, we will also invite the Meshtastic team to develop official firmware, ensuring it will fully support all Meshtastic features."
update---the meshtastic version products of Crowpanel advance 7/5 inch has been deleted from our website to avoid confusion.
