This is something new? Or after an upgrade?
I have something similar going on with my esp32s, haven't gotten around to chasing up a fix myself or details to pass onto you yet though. It first started six months ago when I was testing, so probably an earlier firmware than 45N at the time, but that's what it's on now. I'll try to chase up some details over the next few days when I can spend some time in the shed.

It is possible it dropped a packet which causes BC to timeout, but then can be successfully pinged. You might run an infinite ping along side BC and see if it ever drops.

Also, can you connect a computer, put it in debug and see what signal strength it is reporting?

I don't think there is an issue with WiFi on ESP32. Running 45O on a test bench, which (to the best of my knowledge) does not have anything different with respect to radio compared to 45N. Occasionally the libraries are updated which has known to break things. You can upgrade to 45O it if you like - it is in the package on the website. On my test bench ESP32, the RSSI is running -55 to -60, which is not that strong.

Ok so to clarify, The ESP32 can power the RP-3 directly using one of the 3.3V pins?
I have 2 RP-3 connected to a single ESP32 this way, and sometimes on power-up I have to disconnect one before the ESP becomes reachable, then connect it and all works fine... the ESP32 is powered via USB, and I need to ensure I am using the 3.3v pin... multiple other ESP32 variants with single RP-3 are working fine...

Could you post a Part's List and where you got them?
It has been some time since I put this together but it was an Uno R3, 1602 LCD Keypad shield, MCP4725 DAC, HX711 load cell amplifier, your choice of controller mount, power supply, wiring, enclosure, etc. I got most of this off of Amazon except for the spark fun load cell amplifiers. One can get more than one HX711 on an Uno but I didn't bother to work it out as I wanted two continuous local displays and this stuff isn't terribly expensive. The analog output over to the BC controller is a bit of a brute force mechanism given the way it goes back and forth through analog/digital/analog conversions in the signal path but it does work. There are other mechanisms now with the ability to bring data values in to BC as per methods described in this thread. In that case, you would eliminate the MCP4725 and need to add an ethernet shield presumably to get the data over to BC.
