We are using ANT for our communications and we have a few questions.
We have a few different nrf52 modules. We started with a sparkfun nrf52832. For the integrated 5v regulator we moved to the nrf52840, tried the
holyiot 18010 (advertised as 5v capable but is NOT). Then moved on to the
E73.
We've set the TX power to +8dBm but the RSSI is around -75 to -80dBm over a distance of 4 meters with two 18010 modules(or the sparkfun messaging to a 18010), the E73 modules has -75 to -80dBm over a distance of 50 centimeters messaging to a 18010. Because of the bad antenna on the E73 we are planning to use a
MDBT50Q-U1M
The
wiki states a range of 30 meters at 0 dBm.
I know noise is an issue but this is a very big difference 30m@0dBm versus 4m@+8dBm.
How can we achieve a 30m range?.
Your assistance is greatly appreciated!
