Which external antena have you used? I see this as the only option. With standard wemos-32 with build in antena i can get reliable range up to 1m (with no direct view). This way i would need to install like 2 esp gateways in a room instead as preferred 1-2 per floor.
Hi, is it possible maybe to work on this power setting from your site (or anyone else)? Having a direct line of sight is hard to achieve and increasing range with this would be a huge advantage in my case. I don’t care of the power consumption as i got it directly connected to the grid and hidden in a closet.
Sure, i’ve already seen the wroom-32U version witch is interesting to check but anyway in my present usecase any (1-2meter) of incresed range would be enought. I believe this would be beneficial as well to the other users to have this parameters enabled so they could play with range (increase or decrease) acording individual needs.
On previous post i saw that this try was not giving any visible efects so definately some advanced user as you @1technophile would need to have a look on this feature.
while the wroom-32U with an external antenna might be overkill, I have recently ordered 2 WROOM-32D, which, according to Espressif, has
The antenna design has also changed. The result is better RF performance.
or from the tech spec sheet:
ESP32-WROOM-32D, compared with ESP32-WROOM-32, has been improved in the following aspects: TX Power, RX sensitivity, EVM, Band Edge and Spurious Emission.
And I can confirm, replacing a ‘standard’ ESP32-WROOM-32 with a new ESP32-WROOM-32D, at the same location, the reception sensitivity of my usual beacon has improved from an average -82db to now an average -65db.
So maybe this model could help with your 1-2meter range issue as well.
Just make sure to break off the PCB board underneath the antenna, if it also has it there for package and postage safety, so that the antenna is fully free, as it’s supposed to be for this model - the PCB has a predetermined breaking point there.
I compared ESP32-WROOM-32U & ESP32-WROOM-32D. ‘U’ version works similar to D so haven’t found it as ‘overkill’.For D I haven’t noticed any break point. My antena looks to be attached to main frame and sticks a little bit outside the contur.in this situation I would recommend D as only one worth buying.
I only meant the external antenna, which usually doesn’t come with the ESP32-WROOM-32U package as possible overkill of thing to get and spend on, as you stated you would only need 1-2 meters of additional range;)
Yes, my PCB antenna totally sticks out over the borad as well, as in this image
but when I received two ESP32-WROOM-32D units, they both had the board underneath extend all the way under the antenna, so I had to break it off. I think different vendors might do that, so that the quite thin antenna itself doesn’t break off during the package and posting process, others obviously don’t seem to do that.
I agree, the ESP32-WROOM-32D is the go to ESP32 variation for me in the future.
Have a look at ilgrank’s measurements. I can confirm that the Seeed Studio XIAO ESP32C3 is doing very well. From my 8 LYWSD03MMC-ATC-ble sensors only the most distant one from upstairs is missing or rather seldomly detected.
Any board containing the ESP32-C3-WROOM-02 module as my ESP32-C3-DevKitC-02 should have a good BLE range as well.
