Selecting BLE Module

Hello,

My team is looking for a Bluetooth low energy module that meets the following requirements:

1. Bluetooth 5.0 specification

2. Decompresses images/videos with max size of 30 MB

3. Establishes a connection with a LCD/LED display

4. Establishes a connection with an optic sensor

5. Includes its’ own receiving antenna with a rectifier and transmitting antenna with an oscillator that supports frequency band of 2.4 GHz

6. Ability to interface with an external flash that will store 30 MB max file space

7. Includes a temperature control system

While we have reviewed various chips and modules such as the ARM Cortex - M33 DA1469x series (DA14697 specifically), we believe we are not utilizing multiple functionalities and we are hoping Dialog Semiconductor engineers could help us narrow down the options for a BLE chip that suits our needs.

Please feel free to email us atalphawavetechnologies@gmail.comfor further discussion. We look forward to hearing from you.

Thank you in Advance

Thank you very much. Like

Thank you very much. Like mentioned, based on my team's discretion, the DA14697 chip would likely function to our needs however we believe multiple functions or pins specifically would be wasted. The most important application for our product is to simply be able to transfer an image/video from a mobile device to the slave device and display the content of that image/video on the screen. The max file size is 30 MB like mentioned. We did not find a chip that could support the 30 MB storage, therefore we are thinking of utilizing external flash storage. Therefore if the module is compatible with external flash drives, that would be optimal. I truly look forward to hearing from you. Once again, i sincerely appreciate your aid.
