TX power for CC1352P2 CC2652P router firmware

[bkupidura]

Hey, Can you please share what tx power is set in CC1352P2_CC2652P_other_router_20210128.hex?

Currently im tessting CC2652P as a router, it works stable but i think that it has lower radio tx power than my old CC2530+CC2591 - which is surprising ;)

Yes, the firmware for cc2652r works. Sorry, but I don't have info about sonoff s26R2ZB.

Thanks @ptvoinfo

Sorry, but I don't have info about sonoff s26R2ZB.

FYI, ITead Sonoff S26R2ZB ZigBee Smart Plugs (S26R2ZBTPG/S26R2ZBTPF/S26R2ZBTPE) is also based on a new radio module with CC2652P (CC2652 P1F) but it has ceramic chip antenna so it does not look to have the same exact radio module design, or does it?

@Hedda, note that the module on your pictures has exactly the same design flaw/optimization as described in https://github.com/ptvoinfo/zigbee-configurable-firmware/issues/96#issuecomment-1056704722 (ptvo blog post), therefore enabling the power amplifier will result in working chip/FW, but no transmitted packets.

So to resolve https://github.com/Koenkk/zigbee2mqtt/issues/10282 it then probably very likely that selecting CC2652R chip type in the PTVO firmware configurator will result in a working firmware image on the ITead Sonoff S26R2ZB ZigBee Smart Plug similar to the new Sonoff ZBMINI (01MINIZB) as both use CC2652P (CC2652 P1F) chip model and their radio modules have same design "optimizations"?

Manually configuring the transmit power to 5 dBm or less in the firmware should probably also work?

@ptvoinfo there have been a few commits on https://github.com/ptvoinfo/zigbee-configurable-firmware but it seems like the changelog on the blog hasn't been updated in a while.

Are any of the most recent commits relevant for the router firmware (in my case, originally Dec 2021)? Thanks.

[ptvoinfo]

@ruimarinho All these changes are relevant to my firmware, where you can build a router too.

5dbm, currently this is not configurable, to change you have recompile: https://github.com/Koenkk/Z-Stack-firmware/blob/master/coordinator/Z-Stack_3.x.0/COMPILE.md

See https://github.com/Koenkk/Z-Stack-firmware/issues/341 for request + discussion about having a similar configurable feature in Koenkk's Z-Stack Zigbee Router firmware -> https://github.com/Koenkk/Z-Stack-firmware/issues/341
