Galaxy S I9000 send get response form AT commands

由 大城市里の小女人 提交于 2019-12-07 17:53:35
问题 I am trying to send AT commands on Galaxy S (I9000). The problem is that I am not sure which device is the modem. Searching into file /system/build.prop, i get that the device used by rild is /dev/ttyS0 (rild.libargs=-d /dev/ttyS0). But there is no ttyS0 file into /dev directory, and as a result I get an error when trying to send commands to it. Executing the command cat /proc/tty/drivers I get the following results: /dev/tty /dev/tty 5 0 system:/dev/tty /dev/console /dev/console 5 1 system

How to read SMS using AT on an embedded system with limited memory?

问题 I'm developing a piece of embedded software, which also communicates with a modem through the AT protocol. Now I want to read messages, but I have come across a problem with my memory capacity. It could be that there are multiple messages for me, and using the AT command set, I get them returned all at once. I do not have the memory capacity to store them all to process them (I only have 1KB or so). See the examples here: http://www.smssolutions.net/tutorials/gsm/receivesmsat/ I send AT+CMGL=

问题 im trying to control a bluetooth bracelet with vibration function via HFP (hands free profile) in Android. I've been able to connect to the bracelet and access the input- and outputstream.
