Posted at 2019-03-04 by @gfwilliams Are you running off a battery? If you just power it from 3.3v (or the dev board) the modem gets no power so doesn't work. Posted at 2019-03-04 by user97438 I am using Battery 18650, 3.7V 3600maAH , so it's not power problem. Posted at 2019-03-04 by @gfwilliams Did you use the exact code from: https://www.espruino.com/RAK8212#sms Or did you modify it somehow? Posted at 2019-03-05 by user97438 we used the same codes as above, finally we found the error also was caused by sim card socket ,there is no any error if we push SIM card. but we still can not send out SMS or received SMS . can you confirm BG96 can work in Singapore? Posted at 2019-03-05 by user97438 we confirmed we can use the same SIM card to send /receive SMS on hand-phone Posted at 2019-03-05 by @gfwilliams You're better off asking RAK Wireless for support on stuff like this - that's definitely more of a hardware question. Posted at 2019-03-13 by user97438 we bought new RAK8212 board, now still can not send out /receive SMS . there have error " CMGL ERROR Test mmmm ", sometimes there is no any error but also can not send out /receive SMS . Posted at 2019-03-13 by @gfwilliams What changed between:
and
It seems that a week ago you had this working fine? Posted at 2019-03-13 by user97438 not, it only can run /but get error messages. The old board got a lot of exceptions since the SIM card contact point not good Posted at 2019-03-13 by @gfwilliams I just tested yet again with mine, and it works fine. I imagine the problem is that your SIM card is an NB-IoT SIM that doesn't support SMS text messages. Maybe try a SIM card from your phone? Posted at 2019-03-13 by user97438 My SIM Card is CAT-M1, I can use it to send out /receive SMS on the Hand-phone Posted at 2022-04-07 by user142393 Once such errors occur to me, it means that it is a sign that I don't have longer use my number. How do I know this isn't a scam or something? |
