TUYA Blood Pressure Monitor BLE Readings - Smaller Chip Inquiry

Quote:

Report record-type data (0xE0)
- If the module is offline when receiving reported data from the MCU, it will save the data to its flash memory and send the stranded data after going online. After the last piece of stranded data is sent to the cloud, the module will release the cache.
- The module can cache up to N pieces of DP data. When the limit is reached, the newest record will overwrite the oldest one.
-> The nRF52832 and BK3431Q based modules can store up to 80 pieces of data, with a maximum length of 200 bytes per piece.
-> The BK3432 based modules can store up to 32 pieces of data, with a maximum length of 32 bytes per piece.
- The time drift of the module’s internal clock is less than one minute in 24 hours. The module will sync its clock with the server time each time it is connected to the cloud. If you require highly accurate time, you can report data using the MCU’s timestamp.
