Frequently Asked Questions

★Question:Can two WIFI radios communicate directly with each other; How to configure it if possible.

Answer:sure; The manual provides detailed instructions on how to set up APSSTATION, including how to connect one as a Station and the other as an AP.

★ Question: Does it support MQTT or Azure? If not, is there any way to do it?

Answer:MQTT and Azure belong to the upper layer protocol references of the Internet of Things, and customers can implement the protocol content on E103-W02

★Question:May I ask if the module pins are compatible with ESP-12? How big is Flash?

Answer:Our E103-W01 pin is compatible with ESP-12F, and our external flash size is 1MB.

★ Q: Is it possible to implement data transmission from one hundred modules on a device to a server?

Answer:tolerable.

★Question:What is the reason why the WIFI module cannot ping the external IP address when the module is connected to the router and the router is connected to the external network?

Answer:Cannot ping the external network.

★Question:How long can the maximum sleep time be set before the module is automatically awakened, for example, can it be set to 4 hours before waking up?

Answer:It can meet the requirement of 4 hours wake-up time for configuration, but the longest time has not been tested. You can test it yourself.

★Question:How to configure a module to enter a low-power state and wake up the module on a scheduled basis?

Answer:The manual contains relevant AT command setting methods and instructions, which belong to timed wake-up, but not periodic.

★Question:I cannot modify the module name. After successfully modifying it, I used the AT command to check if it was the name I wanted. However, when I scanned it with my phone, the name was still "CDEBYTE". After powering it on countless times, I found that the name had not changed. This module cannot be scanned by Bluetooth modules from other companies, nor can it be scanned by WIN10 computers. It can only be scanned by my Xiaomi phone. I have tried both single role and multi role modes, but this module cannot be scanned.

Answer:1. Computers need to have BLE function to scan our devices. Generally, computers use classic Bluetooth, which cannot be scanned; 2. Recommend using the "BLE Deng" app software for testing; 3. Please ensure that the power supply is sufficiently stable; 4. Our E74 is currently in the Xiaomi series of smartphones; 5. The Bluetooth name can be modified, and the app uses the testing software lightblue; It is recommended to use lightblue and BLE assistant for testing software IOS, and BLE deng for Android.

★ Question: In UDP mode, it is possible to connect, but communication is not possible. What is the reason for not receiving data when sending?

Answer:You can first check if the port information configured for UDP socket matches that of the sender; Try sending data to each other. Early versions require customer service to send data to the server first. It is recommended to upgrade to the latest version V1.5 based on our customer information to solve the problem.

★ Question: Do you have performance testing data for the module?

Answer:We tested EVM, frequency accuracy, harmonic distortion, power adaptability, and standing wave ratio. The throughput of WiFi has not been tested.

★ Question: What is the AT command for sending data? I couldn't find it in the manual

Answer:In transparent transmission mode, simply send the data directly. No instruction required.

★ Question: Can the second pin on the module, which is the ADC input pin, be used to detect battery voltage?

Answer:Can be used to detect voltage, with a detection range of 0.0V~1.0V voltage; Our user manual provides detailed instructions, please refer to the user manual.

★ Question: Is the LED indicator light on the module a power indicator light or a signal indicator light?

Answer:Intermittent Double Flashing: The module cannot connect to the AP access point. Intermittent Single Flashing: The module has connected to the AP access point but cannot connect to the TCP server. Off: The module has connected to the AP and the server, which is the status indicator light; Please refer to the product manual for details.
