Migrating from Conbee II to Sonoff Dongle P help

[drift (T)]

The issue I’m having is that the Sonoff Dongle P range is quite poor compared to the Conbee. I placed the Mini PC w/ the Sonoff at the same spot as the Pi 4 with Conbee stick, and only paired one Aqara door sensor which is outside, and the LQI was 0, whereas the Conbee was at 255 LQI. Using Z2M.

I’m confused how the Conbee without an antenna, could have better range than the Sonoff. Don’t know if I should keep the Sonoff (I did get it during Prime day which included an extra dongle) . Tried installing the Conbee with Z2M, and it kept failing, even with clean install.

I didn’t update the firmware on the Sonoff yet, or does the E have better range. Don’t know what to do. The Sonoff is way easier to setup though.

i don’t have a conbee so i can’t attest to that. however the sonoff does have the ability to modify the transmit power. that might affect its lqi at least on the transmit side.

Sonoff dongle plus router/repeater - changing TX power

Hi all I was able to flash CC1352P2_CC2652P_launchpad_router_20221102 onto my Sonoff dongle pluses, and they seem to work fine so far. This version is supposed to allow changing of TX power from default of 9dBm. I see there’s a reference to: Set the transmit power through the serial port command SYS_SET_TX_POW If anyone has done this before, or knows what the above means, please let me know, e.g what application/command line to use. I tried SmartRF Studio 7 with the dongle plugged in via USB …

Different chipsets calculate LQI different, so you can’t really compare LQI in this case.

Alright thanks. I’ll try changing the tx power plus I’ll switch the other dongle to router mode. I could pair any device to the router dongle right and it’ll stick to that one?
