I have a work around. I declared the elements in the structure text as integers then using a if/else statement I set the element to a number based on the drive status as shown below. I have a similar statement for the steering. I then can send the structured text to the receiver ESP32 then set the d...

I didn't think it was necessary to go into details of what isn't working, but if you look at the end of the code under the comment "Set values to send" are a couple of the attempts. I think part of the problem is the declaration of the variables in the structured message and how I am formatting that...

I am building a sip & puff control system so that a quadriplegic can control a RC boat or car. I had it working with Arduino Nanos and NRF24L Wi-Fi modules. Now I am converting it to use a ESP32 and ESP_NOW for communications, the NRF24L's give me troubles now and then plus it reduces the hardware I...

Right now the ESP32 is laying on a breadboard, the Lora antenna is on a small angle bracket a few inches away and about an inch or so higher than the ESP. I'll try to reposition them both. I'll look into setting up the debug.

Thanks for the suggestions

I'm working on a Lora system, I have a sending unit using a Sparkfun Firebeetle with a BME280 sensor. That sends the values to a the base unit in my house using a ESP32 Dev module. That part is working fine. I've now added MQTT to the base unit. I have a Raspberry Pi 4 server running Mosquitto and u...

I'm working on a greenhouse monitor, currently I have a BME280 module connected to a ESP32 Dev board, this unit will be battery powered. In the house I have another ESP32 Dev board with a 3.5" TFT display. I connect both to my house WiFi router. I have the monitor connect to the internet to get NTP ...

I installed the AMS1117 with a 330 uF cap across the output and it still doesn't work. Seems like it should, maybe it has to do with this ESP32 board I have some others on order. I do notice that the red LED flickers a bit, maybe as it's drawing current it dips the power although when I put a meter ...

Thanks for all the comments. I had posted a reply earlier today but it does not appear to be on the thread. I changed the HT-7333 with a TC1262, that has a 500ma output but that did not help. I disconnected the NRF24L01 but it still needs more power. I have ordered some AMS1171 LSO's and 330uf caps,...

Thanks for all the comments, here's what I've done. The original circuit I am using used a MCP1700 LDO, also a 250 ma output, so I've changed mine to a TC1262-3.3v which has a 500 ma output, put it still doesn't work, actually it did for 2 sleep cycles set for 30 seconds, then stopped. I think betwe...

I am working on a remote greenhouse monitor. I have a BME280 sensor connected to a ESP32 development board. I can connect the ESP32 via WiFi to my home router and send the readings to ThinkSpeak. I also have a NRF24L01 connected that sends the readings to a Arduino Mega that I have a TFT display in ...
