FAQ

A. Q: Bluetooth module support BLE protocol?

Answer:Supported,eh-mb18 is bluetooth dual module.It supports both traditional bluetooth and BLE's bluetooth protocol.


B.Q:How to connect the BLE agreement of EH-MB18.

Answer:Download the "Ehong LINK" APP on apple's APP store to connect to the module.


C.Q: How to start bluetooth protocol?

Answer:Use AT+PF command to switch the bluetooth protocol to be used.


Q:Does bluetooth support OTA?

Answer:If you want to support the OTA function, first of all, the module should hang a SPI flash to store the updated data.


E,Q:EH-MB18 support internal charge?

Answer:Because the internal charging current is small, the module does not support internal charging, and it is recommended to use the external charging circuit directly.
