Frequently Asked Questions |
|
★Question:Used to upgrade programs, files of over 100k, at 2.4Kbps, 64Byte per second, require continuous transmission for over 30 minutes. Does it support continuous transmission? Will the module burn out? |
| Answer:Take good measures to dissipate heat, it won't burn out. |
| ★ Question: What is the minimum size that can be achieved if customized under the same performance? |
| Answer:The current volume is 36mm * 25mm. If the transmission distance is not very far, it is recommended to use low-power ones, as high-power ones have a smaller volume. |
| ★Question:The maximum power amplifier of the chip is 20dB. How do we turn on the additional power amplifier? Does it automatically become 30dBm when set to 20dBm? |
|
Answer:The power can be directly set to 20dBm by the RF chip, and TXEN/RXEN can be enabled during transmission and reception. |
| ★ Question:Terminal data packets, 20 bytes per packet, 3km distance, 1000x20 gateway, can be sent separately to meet the requirements? |
|
Answer:Many to one usually adopts a polling method, with a slightly longer polling period of 1000. At an airspeed of 2.4K, there is approximately one polling per second. It can increase airspeed and shorten time. 19.2 airspeed 1 second polling of 10. |
