Monitoring station 1 (QR1) 27/04/2021 at night

  1. The battery is low voltage (lower than 11.5V), which is indicated by the fast flash of the regulator status. And the system is disconnected due to low voltage protection. The return voltage for over-discharging is 12.5V, which means the system should be automatically switched on once the battery is charging and the voltage is higher than 12.5V.

  2. Hostapd does not start at reboot when Pi zero has been set as WiFi router Run this command line to make sure that the hostapd configuration is completed sudo /usr/sbin/hostapd -dd /etc/hostapd/hostapd.conf

A warning like below when you login a pi "-bash: warning: set locale: LC_ALL: cannot change locale (en_US)"

A solution is:

Edit /etc/locale.gen and uncomment the line with en_US.UTF-8 e.g. sudo nano /etc/locale.gen
uncomment line by deleting leading #

Problem:

pi@sa3_camera:~ $ tmux
tmux: invalid LC_ALL, LC_CTYPE or LANG

solution:

apt-get install locales
dpkg-reconfigure locales

chose en_US.UTF-8 and en_GB.UTF-8
