Hello,
I''m investigating using PUART-Control in a battery powered sensor application. Will the PUART-Control software go into a low power mode when nothing is happening? If so, will it wake up when a Master connects to it or when it receives a serial message? I looked through the code but didn't see any mention of this.
Thanks,
Derek
Show LessHello,
I was looking through the examples and I saw the puart_control example. Two questions:
1. Does this example support power management? As in, can I use it with a battery powered device, and put the BCM20737 to sleep?
2. Is there any example code for a host MCU for doing some of the basic functions? Like Advertise, Read/Write, etc?
Thanks,
Derek
Show LessHello, as a continuation of the original thread here: WsRsaSign.exe can't run in Win7 64bit
I find another question during test OTA without secure, that is:
h
I try to find a apk that can help me to test OTA, then I find OTA_Android_Sample_NoSecure.zip from WICED Smart BCM92073X OTA Firmware Upgrade (2).
I use ota_firmware_upgrade project in chip 737, When I try to start OTA, it also fail, so I trace the process, it fail in "Bad Download len:1", then I comment these code, the OTA is successful.
// if (len < 3)
// {
// ble_trace1("\rBad Download len:%d", len);
// return (FALSE);
// }
so I wanna know where wrong is, and which code I should refer to,
PS: my OTA bin file's size is about 10kb, is it too small to cause this problem?
Thanks.
Show LessIn some cases, I failed to write empty eeprom in our PCB with BCM20737.
Commnd line tools are used in writing eeprom.
I add recover option in WICED SDK . I manage to write empty eeprom.
Can I add recover option in command line tool ?
Thanks in advance.
Show LessI have a problem about writing to bcm20737s.
I don't know the reason why, but frequently mistake writing to bcm20737s on my original pcb using UART.
Is there any special condition if I want to write always correctly(for example: writing cable must be shorter than 3cm...?)
If you know any document about this problem, please show me...
Show Less====================
SDK: 2.2.1
Tag: 920737.
app: OTA hello-sensor app .
OTA firmware size ~ 30KB.
====================
Description:
Our customer encounters one problem, they buy 3 devices
and put into 3 rooms, each device with its Tx power set by max. 4-dbm.
First we put devices beside client handset scanning and check client Rx ~ -50~ -60 dbm.
but after put them away from client, distance approximately 20m 25m 35m (of which
Rx is -70dbm, -80dbm and -95dbm) and the third one is easily disconnected.
Investigation:
- already set blecm_setTxPowerInADV(4) for 4-dbm.
- is any fading issue there in 20737 tag, any parameter related with for adjustment?
Show LessWe have a 20736 Tag3 board,and when test with it ,find battery voltage is allway 88 with app "hello server".
What's wrong with it?If we want detect battery voltage,how to work?Any hardware to add?
Show LessI want to use a spectrum analyzer to measure the carrier freq offset and drift and other physical layer measurement with the Wiced Sense at both NOC and EOC. I want to know what document, test software, setting and command that I should use to set it into hte test mode for the Tx measurement. Appreciated if someone can provide any input to assist me.
