Long range BLE module

[Answer]

Hello,

I have purchased a Bluetooth module before from Cypress "CY8CKIT-143A". I was able to operate it with 1mA to send a temperature signal for 20 meters. How to run the temperature sensor (Thyrmesotr)  example was available in the tutorial which was easy to understand. Now I am looking for a similar module with Ultra-low-power to send a signal 250 meters or more. I heard that a new Bluetooth 5.0 module is being released and I also read about IROC™ Bluetooth Modules. However, I want to listen to your suggestions. what is the lowest power-consuming module that operates around the 250meter range?

(I would like to only send one signal per 1 second in an open field)

Thank you,

You may take a look at the modules below whose range is 400m in full line-of-sight environment, free of obstacles or interference sources. We also have some modules whose range is 1km in the same condition. The power consumption is under 100uA with 1-second connection interval. You can find the details in the module datasheet:
