Any way to know RSSI?

Hi, I’ve built special Radio Dongle firmware that now sends also RSSI to MQTT with every received message. You can fine tune the placement of remote nodes with really weak signal.

Communication range

I’ve managed to get working RSSI indicator. RSSI says how strong the signal is. The lower the weaker signal. 50 cm from dongle: -50 dBm 2m from dongle: -54 dBm I was not able to compare RSSI for node FW with 10 and 11.6 dBm, the values we’re too close to say it had any advantage from few meters. Signal is lost somewhere around -95 to -102 dBm in my case, when I’m behind many walls. Here is the patch for SDK repository and compiled firmware for Radio Dongle. usb-dongle-with-rssi.bin (99.3 …

Hello to everyone,
@owar @owarek @mlnz @jakubcizek

we have added Radio Dongle and Core Module with external antennas in our CZ/EN shop:

• https://obchod.hardwario.cz/core-module-ea/
• https://obchod.hardwario.cz/radio-dongle-ea/
• https://obchod.hardwario.cz/anteny/

In most cases you can upgrade just dongle with for example this antenna https://obchod.hardwario.cz/interni-lpwan-antena-microcoax-u-fl/ to get around 30-40% range increase based on my tests.
