If that doesn’t compile for you, update your TinyGSM library or just delete lines 87-92 to remove the forceModemBaud command, which needs the version of TinyGSM within the last few weeks.
It it’s working for you, comment out the section that resets the modem to defaults (lines 107-126) and run it one more time to get the modem to 9600. It should…[Read more]

Use 3.3V to power the WiFi bee and make sure that you’re adapter uses 3.3V logic. The 0.5A most USB ports can provide should be enough for the WiFi bee without browning out. You are seeing the lights on the bee go on, right?
This script worked for me to force the baud rate on three different WiFi Bee’s. The script forces the baud rate and th…[Read more]

I’ve tried some more witht hat code and no luck. So I decided to confrim the AT firmware and I’m not sure if I did or not. Using a USB to TTL I connected directly to the Wifif Bee and used Putty. I did see some text and a brownout warning on the screen. So I used the TTL for RX and TX and I connected a 3.7V Lipo battery to VCC and GND and also the…[Read more]

@ensign Thanks for the great question. So prior to 2018, SVPA was building its own sensors. After 2018 the program began using Senix Brand ultrasonic sensors on a private MTS system, reading to configured […]

Thank you very much Sara. I have tried something like that before (but likely not quite rightly coded). This failed to switch baud rates too unfortunately. I have tried this on 3 out of 4 wifi bees that I have (but just one with you sketch so far) and no luck, that’s how I ended up asking about the firmware.
Did your sketch in a hurry, so will…[Read more]

Once you’ve successfully changed the WiFi bee’s baud rate, it will stay at the slower baud. You should only have to reset the baud rate if you factory reset the bee or update it’s firmware – neither of which you can do by accident.

The WiFi bee should have the AT firmware on it. The problem probably is the baud rate. The default baud rate for the ESP32 (the brain on the WiFi bee) is 115200. That’s too fast for stable communication with the 8MHz Mayfly. The Mayfly can usually *talk* fairly accurately at 115200, but it can’t listen that fast. The auto-baud function depends o…[Read more]

Hi, I have a Mayfly 1.1 and a ESP32 WiFi Bee purchased from EnviroDIY recently, also a Hydros21 CTD. Having lots of trouble getting it to work. Using the EnvirDIY_Monitoring_Kit sketch from https://github.com/EnviroDIY/ModularSensors/commit/f149a372ae47d95d474971abc25dd378bd332ecf. Though I have also tried other ones (possibly older) from…[Read more]
