The es-Wifi module is based on a simple AT command set that is used to communicate with the module. You can use a low cost 8/16/32 bit microcontroller to control the eS-WiFi module.

We currently support = WEP, WPA, WPA2-PSK

The transmit power is set to a max output power level of 18 dBm. This level is compliant with the FCC and CE regulatory standards.

The range varies depending on what antenna scheme you choice. The options are PCB etch and external. The distance depends on environmental conditions, but the range is approximately 250 meters line of sight with up to 5 Mbps Wi-Fi connection … Continue reading “What is the range of your es-Wifi modules?”

1. Set Access Point SSID 2. Set Access Point Password 3. Set Access Point Security Mode 4. Use DHCP? 5. Join Network Ex. C1=eS-WiFI_Demo Set SSID C2=LetMeInNow    Set Password C3=4    WPA2-Mixed C4=1    Use DHCP C0    Join

1. Set Protocol to UDP 2. Set Local port number 3. Start UDP Comm Sever EX. P1=1    Select UDP Protocol P2=5024     Set Port 5024 P5=1    Start UDP Comm Server

The base part number is ISM420R1-C33. The ROM Code part number can be read from the GPS in OSP (Sirf Binary) mode only and the version is :  “GS4e -4.1.2-P1”. The GPS will initially come up in OSP at 115200 baud, unless … Continue reading “What is the latest ROM version for the ISM420? How do I read it?”

Function: OSPMID129 Description: Send SiRF MID 129 (Switch to NMEA Protocol) to GPS in OSP mode // where: A0A20018 – Start sequence/Payload length // 81020101000101010501010100010001001000012580 – Payload // 01ABB0B3 – Checksum/End sequence // 81 MID // 02 Mode: 00-Enable NMEA … Continue reading “OPS MID 129 routine (switch from OPS to NMEA) for ISM420-480 EVB”

You need to send a Carriage Return (0x0D) and Line Feed (0x0A) after the checksum (*37) for the SiRF chip to act on the message. Ex: $PSRF100,0,57600,8,1,0*37<CR><LF>
