Thank you and bummer news! The programming and diagnostic center is sound. I am not a first time hobbyist. I have thousands of modules deployed, which we service and support daily. This is a new phenomenon and exclusive to our new deployment with the regulator removed and direct power from 3.6v batt...

The batteries are Saft 3.6v which when brand new, float at about 3.68V. During Sleep, the batteries would hit this float peak voltage. During a wifi operation, they run about 3.55v. In my test station, I use a variable dc power supply and see the gibberish behavior described at 3.3V applied. It soun...

I have a design using the ESP32 WROOM 32D module and have found that a percentage of the devices are Supply Voltage sensitive for operation. This is tested design with tested code and 3000 units in the field. On the newest revision, I removed the voltage regulator since my operation is 3.6v battery ...

Thank you for looking! I have an application using the ESP32 WROOM module. 3000 are in operation with code that uses the wifi to conduct a fetch and post to a server. All the code works well; however with my newest deployment of devices, I am getting units which failed mid operation (such as during ...

How did your port turn out?
I have an up coming project that requires a BACnet RS485 MS/TP slave feature to report a temperature.

Thank you for your reply. Unfortunately, the time to receive an IP address has recently expanded and is not entirely under our control. Trying to understand what criteria is causing the new battery drain condition. It sounds like a long IP wait could contribute.

I also wonder what is the wifi power during an AP scan?

Please help.
Health and regards,

Hello and thank you for your read! I am trying to understand a high battery discharge rate in a battery application which I have been using since 2017. The only new element is how long it takes to get an IP from the AP. It used to be in milliseconds and is now averaging 12 seconds. The battery drain...

Hello and I am glad that your solution is working. May I suggest our solution as an alternative. We have a situation where there are many AP's throughout our facility with the same SSID. It is important for our esp32 device to connect to the strongest AP with the appropriate SSID. To accomplish this...

very interesting point. When looking at the monitor output, each time the current is high for Wifi Start, the statement: W (15047) phy_init: failed to load RF calibration data (0x1102), falling back to full calibration is present and when the Wifi Start current is low, this statement is not present....
