I have developed a ble5 long range and meshing product but my life is way to short. using 2-3.6v batteries in parallel and only getting 2 months life in my battery calculations and I know I should be getting a lot more can anyone help me ?
Battery Lifetime Report
For a week
GDM Open Alarm
24 * 7 hours
Wake on GPIOTE input
3.6V 1.2 Ah * 2
Sum = 10.8 * (24 + 280 / 3600) + 2.36 / 1000 * ( 24 * 7 – 24 – 280/3600) = 260.38 mAh
Lifetime = 1200 * 2 / 260.38 * 7 = 64.5 days
Therefore, battery life time is about 2 months
Could you describe your mesh network ? Which nodes are relay node, what is the communication between them ?
As mentioned by Marciano, relay nodes and normal mesh nodes require main power. You can run a low power node on a battery. But this node can't relay mesh message.
You mentioned that with Bluetooth 5 you have longer range, which feature of Bluetooth 5 you used that improve the range ?
Ok I have a transmitter mounted to a garage door using 2-3.6v batteries in paraelle when door is closed transmitter is in sleep mode when door opens transmitter awakens and send signal to receiver (nodes) . the receiver starts to blink LED lights and make a beeping noise. the distance in range with just one node is about 90 feet indoors then another node further. the receiver nodes are plugged into a usb wall charger and have full power supply at all times. but battery life is way to short. I am not sure what you mean by what feature of bee long range I am using ? we are using the blue nrf52840 chip with long range and meshing. the nodes are not running on battery only the transmitter. and it is in beacon mode.
Could you clarify are you really using mesh or you are just using Bluetooth Low Energy (start network, point to point, one central node and multiple peripheral node) ?
If you are using mesh, which technology are you using ? How many node in the network ?
Could you explain what is the "Open Alarm" and "Close Alarm" ? Why the duration is 24 hours and 280s ? Even if the duration of the alarm is 24 hours, you don't need to transmit data all the time, continuously for 24 hours, correct ? Please describe in more detail the "Long Range" mode you are using, what radio configuration do you have ? Which output power ?
