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 on my Windows PC, but the device couldn’t be detected.
That is correct. But I recommend leaving them as default as it only makes them louder but not listen better. That is, it only amplifies radio transmission signal and not reception so devices that can can hear it might not have strong enough radios to reply back. Solution is instead to add more Zigbee router devices → Zigbee networks: how to guide for avoiding interference and optimize for getting better range + coverage
Thank you @Hedda, I must admit that LQI values are much better since i flashed with 20221226 firmware (all values are +20 or +30 higher). I was previously on stock firmware (february 2021).
I will play with tx_power setting only if i lost devices (it is not the case for the moment)
Another tip is that can possibly get better reception by replacing the external antenna with one of higher quality, but again, the best way for Zigbee is still just to add many more known good Zigbee Router devices to build out your Zigbee network mesh as well do everything you can to avoid interference close to the Zigbee Coordinator and all the devices → Guide for Zigbee interference avoidance and network range/coverage optimization
Pretty sure the default changed from +5db to +9db somewhere in between.
Generally I agree with @hedda though, trying to bump higher may cause more harm than good. Worth testing, but don’t put too much faith in LQI numbers. LQI as a diagnostic is better than nothing, but not by much.
