  === 6.2.1  Battery Note ===
++
  The Li-SICO battery is designed for small current / long period applications. It is not good to use a high current, short period transmit method. The recommended minimum period for use of this battery is 5 minutes. If you use a shorter period to transmit LoRa, then the battery life may be decreased.

  === 6.2.2  Replace the battery ===

  (((
  You can change the battery in GroPoint Air. The type of battery is not limited as long as the output is between 3v to 3.6v.

--The default battery pack of GroPoint Air includes a ER26500 plus supercapacitor. If users can’t find this pack locally, they can find ER26500 or equivalence, which will also work in most cases. The SPC can enlarge the battery life for high-frequency use (update period below 5 minutes).

  == 8.2  Why i see the payload is 7FFF? ==

  The device will judge the length of the data received by the serial port. If the length of the received data is 0, it means that there is a problem with the sensor communication or the sensor is not connected properly, it is invalid data, and the uploaded data is 7FFF.
