Is there a way to increase power?

Question

Using firmware 1.0.1.8 We are using a point to point link sending data in udp mode. We are finding that packets are randomly not getting through. It is sending 66 packets a second. It is as though it uses just enough power to send almost all the packets, but not quite all of them. If we put the 2 modules close together, all the packets get through. Further away, it drops some, and it seems that increasing the distance does not make much difference - it increases the power to get most of them through, but not quite enough. Is there a way to force the module to maintain a higher power transmission ? This is the response to at+mwifips at+mwifips=? 0,0 [OK] Are there any other at commands that might be influential ?

Perhaps you could use the at command AT+WBGN wizwiki.net/wiki/doku.php?id=pro … et#at_wbgn I don’t know how to use it though, the website does not give any details, just recommends that you should not use it unless it’s absolutely necessary - in your case it might be…

Hi anglial How about trying it again after changing the antenna-option? Try it using a dipole antenna. Issue <AT+WANT=0> command. (Fix a antenna type instead of auto-antenna) AT+WANT Antenna Configuration =? or = (0:uFL,1:PA,3:Auto)

Thanks I will try using the AT+WANT command today. I would like to see what affect AT+WBGN has as well The AT+WBGN command accepts 0,1 or 2 What do the 0,1 and 2 refer to ? Is there a default ? at+wbgn=0 [OK] at+wbgn=1 [OK] at+wbgn=2 [OK] at+wbgn=3 [ERROR: INVALID INPUT] at+wbgn=? [ERROR: INVALID INPUT]

Hello anglial You can fix a b/g/n WiFi mode using below command. You should issue this command before AT+WJOIN. But, I’m not sure that this can solve your problem. AT+WBGN : WiFi 802.11bgn mode Configuration = (0:bgn, 1:bg, 2:b) Ex) AT+WBGN=2 [OK]
